PostgreSQL 11.0 Installation Guide PostgreSQL 11.0 Language Pack Guide. PostgreSQL is the world’s most advanced open source database and the fourth most popular database. In development for more than 20 years, PostgreSQL is managed by a well-organized and highly principled and experienced open source community. I installed pgAdmin 4 as part of the postgres installer for Windows. PgAdmin is now telling me there is a newer version (4.84.5 which I have). However, there is no built in upgrade functionalit. PostgreSQL: 9.6 64-bit. PostGIS: 2.3.1. Notes: 2.3.1 is the only version available on StackBuilder for 9.6, although in principle I could downgrade to an archived 2.3.0 from OSGEO's installer archives, but that's as close as I can get to matching versions (which it turns out would not resolve anything anyhow). The PostgreSQL UPDATE Query is used to modify the existing records in a table. You can use WHERE clause with UPDATE query to update the selected rows. Otherwise, all the rows would be updated. The basic syntax of UPDATE query with WHERE clause is as follows −.

I'm using the PostgreSQL database for my Ruby on Rails application (on Mac OS X 10.9).
Are there any detailed instructions on how to upgrade PostgreSQL database?
I'm afraid I will destroy the data in the database or mess it up.

Assuming you've used home-brew to install and upgrade Postgres, you can perform the following steps.
- Stop current Postgres server:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
- Initialize a new 10.1 database:
initdb /usr/local/var/postgres10.1 -E utf8
- run
pg_upgrade
(note: change bin version if you're upgrading from something other than below):-v
to enable verbose internal logging-d
the old database cluster configuration directory-D
the new database cluster configuration directory-b
the old PostgreSQL executable directory-B
the new PostgreSQL executable directory - Move new data into place:
- Restart Postgres:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
- Check
/usr/local/var/postgres/server.log
for details and to make sure the new server started properly. - Finally, re-install the rails
pg
gem
I suggest you take some time to read the PostgreSQL documentation to understand exactly what you're doing in the above steps to minimize frustrations.

Here is the solution for Ubuntu users
First we have to stop postgresql
Create a new file called /etc/apt/sources.list.d/pgdg.list and add below line
Follow below commands
Now we have everything, just need to upgrade it as below
That's it. Mostly upgraded cluster will run on port number 5433. Check it with below command

Despite all answers above, here goes my 5 cents.
It works on any OS and from any-to-any postgres version.
- Stop any running postgres instance;
- Install the new version and start it; Check if you can connect to the new version as well;
- Change old version's
postgresql.conf
->port
from5432
to5433
; - Start the old version postgres instance;
- Open a terminal and CD to the new version
bin
folder; - Run
pg_dumpall -p 5433 -U <username> | psql -p 5432 -U <username>
- Stop old postgres running instance;

The user manual covers this topic in depth. You can:
pg_upgrade
in-place; orpg_dump
andpg_restore
.
If in doubt, do it with dumps. Don't delete the old data directory, just keep it in case something goes wrong / you make a mistake; that way you can just go back to your unchanged 9.3 install.
For details, see the manual.
If you're stuck, post a detailed question explaining how you're stuck, where, and what you tried first. It depends a bit on how you installed PostgreSQL too, as there are several different 'distributions' of PostgreSQL for OS X (unfortunately). So you'd need to provide that info.

Update: This process is the same for upgrading 9.6 to 10; simply modify the commands to reflect versions
9.6
and 10
, where 9.6
is the old version and 10
is the new version. Be sure to adjust the 'old' and 'new' directories accordingly, too.I just upgraded PostgreSQL 9.5 to 9.6 on Ubuntu and thought I'd share my findings, as there are a couple of OS/package-specific nuances of which to be aware.
(I didn't want to have to dump and restore data manually, so several of the other answers here were not viable.)
In short, the process consists of installing the new version of PostgreSQL alongside the old version (e.g., 9.5 and 9.6), and then running the
pg_upgrade
binary, which is explained in (some) detail at https://www.postgresql.org/docs/9.6/static/pgupgrade.html .The only 'tricky' aspect of
pg_upgrade
is that failure to pass the correct value for an argument, or failure to be logged-in as the correct user or cd
to the correct location before executing a command, may lead to cryptic error messages.On Ubuntu (and probably Debian), provided you are using the 'official' repo,
deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main
, and provided you haven't changed the default filesystem paths or runtime options, the following procedure should do the job.Install the new version (note that we specify the
9.6
, explicitly):Once installation succeeds, both versions will be running side-by-side, but on different ports. The installation output mentions this, at the bottom, but it's easy to overlook:
Stop both server instances (this will stop both at the same time):
Switch to the dedicated PostgreSQL system user:
Move into his home directory (failure to do this will cause errors): Sims 3.
pg_upgrade
requires the following inputs (pg_upgrade --help
tells us this):These inputs may be specified with 'long names', to make them easier to visualize:
We must also pass the
--new-options
switch, because failure to do so results in the following:This occurs because the default configuration options are applied in the absence of this switch, which results in incorrect connection options being used, hence the socket error.
Execute the
pg_upgrade
command from the new PostgreSQL version:Logout of the dedicated system user account:
The upgrade is now complete, but, the new instance will bind to port
5433
(the standard default is 5432
), so keep this in mind if attempting to test the new instance before 'cutting-over' to it.Start the server as normal (again, this will start both the old and new instances):
If you want to make the new version the default, you will need to edit the effective configuration file, e.g.,
/etc/postgresql/9.6/main/postgresql.conf
, and ensure that the port is defined as such:If you do this, either change the old version's port number to
5433
at the same time (before starting the services), or, simply remove the old version (this will not remove your actual database content; you would need to use apt --purge remove postgresql-9.5
for that to happen):The above command will stop all instances, so you'll need to start the new instance one last time with:
As a final point of note, don't forget to consider
pg_upgrade

If you are using homebrew and homebrew services, you can probably just do:
I think this might not work completely if you are using advanced postgres features, but it worked perfectly for me.

Standing on the shoulders of the other poor creatures trodding through this muck, I was able to follow these steps to get back up and running after an upgrade to Yosemite:
Assuming you've used home-brew to install and upgrade Postgres, you can perform the following steps.
- Stop current Postgres server:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
- Initialize a new 9.4 database:
initdb /usr/local/var/postgres9.4 -E utf8
- Install postgres 9.3 (as it was no longer present on my machine):
brew install homebrew/versions/postgresql93
- Tai font vni. Add directories removed during Yosemite upgrade:
mkdir -p /usr/local/var/postgres/{pg_tblspc,pg_twophase,pg_stat_tmp}/touch /usr/local/var/postgres/{pg_tblspc,pg_twophase,pg_stat_tmp}/.keep
- run
pg_upgrade
:pg_upgrade -v -d /usr/local/var/postgres -D /usr/local/var/postgres9.4 -b /usr/local/Cellar/postgresql93/9.3.5/bin/ -B /usr/local/Cellar/postgresql/9.4.0/bin/
- Move new data into place:
- Restart Postgres:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
- Check
/usr/local/var/postgres/server.log
for details and to make sure the new server started properly. - Finally, re-install related libraries?

Looks like the solution has been baked into Homebrew now: Quicken deluxe 2000 download.

This did it for me.
Short and to the point. I honestly don't aim to understand the guts of PostgreSQL, I want to get stuff done.

Invitation programs software free. On Windows I kept facing different errors messages when trying to use
pg_upgrade
. Saved a lot of time for me to just:
- Backup DB
- Uninstall all copies of PostgreSQL
- Install 9.5
- Restore DB

My solution was to do a combination of these two resources:
and
The second one helped more then the first one. Also to not, don't follow the steps as is as some are not necessary.Also, if you are not being able to backup the data via postgres console, you can use alternative approach, and backup it with pgAdmin 3 or some other program, like I did in my case.
Also, the link: https://help.ubuntu.com/stable/serverguide/postgresql.htmlHelped to set the encrypted password and set md5 for authenticating the postgres user.
After all is done, to check the postgres
server
version run in terminal:After entering the password run in postgres terminal:
It will output something like:
For setting and starting postgres I have used command:
And then for restoring database from a file:
Or if doesn't work try with this one:
And if you are using Rails do a
AleksAleksbundle exec rake db:migrate
after pulling the code :)3,1762 gold badges25 silver badges54 bronze badges
I think this is best link for your solution to update postgres to 9.6

On Windows 10 since I had npm, I installed rimraf package.
npm install rimraf -g
Backup all your databases one by one using command
pg_dump -U $username --format=c --file=$mydatabase.sqlc $dbname
Update Postgresql Version Windows
Then Installed Latest PostgreSQL Version i.e. 11.2 which prompted me to use port 5433 this time.
Followed by Uninstall of older versions of PostgreSQL mine was 10. Note the uninstaller may give a warning of not deleting folder
C:PostgreSQL10data
. That's why we have the next step using rimraf to permanently delete the folder and it's sub-folders.change into PostgreSQL install directory and ran the command
rimraf 10
. 10 is a directory name. Note use your older version of PostgreSQL i.e. 9.5 or something.Now add
C:PostgreSQLpg11bin, C:PostgreSQLpg11lib
into the Windows environmental variables. Note my new installed version is 11 thus why I am using pg11
.Navigate to
C:PostgreSQLdatapg11
then open postgresql.conf
edit port = 5433
to port = 5432
Update Postgresql Version Windows
That's it. Open cmd and type
psql -U postgres
You can now restore all your backed databases one by one using the command
pg_restore -U $username --dbname=$databasename $filename
