NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Enter your internal repository url

(this should look similar to

4. Choose your deployment method:

choco upgrade postgresql9 -y --source="'STEP 3 URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade postgresql9 -y --source="'STEP 3 URL'"

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

    name: postgresql9
    state: present
    source: STEP 3 URL

See docs at

chocolatey_package 'postgresql9' do
  action    :install
  version  ''
  source   'STEP 3 URL'

See docs at

Requires Otter Chocolatey Extension. See docs at

cChocoPackageInstaller postgresql9
   Name     = 'postgresql9'
   Ensure   = 'Present'

   Source   = 'STEP 3 URL'

Requires cChoco DSC Resource. See docs at

package { 'postgresql9':

  ensure   => '',
  source   => 'STEP 3 URL',

Requires Puppet Chocolatey Provider module. See docs at

salt '*' chocolatey.install postgresql9 version="" source="STEP 3 URL"

PostgreSQL is an object-relational database management system (ORDBMS) based on POSTGRE, developed at the University of California at Berkeley Computer Science Department. POSTGRES pioneered many concepts that only became available in some commercial database systems much later.

PostgreSQL can be used, modified, and distributed by anyone free of charge for any purpose, be it private, commercial, or academic.


Package parameters

  • /Password - Password to be assigned to the postgres user. If omitted, it will be generated and shown in the install output. PostgreSql installer ignores this parameter if there is existing installation.
  • /NoPath - Do not add postgresql bin directory to the PATH.


  • Test installation (specify your password):
    $Env:PGPASSWORD='test'; '\conninfo' | psql -Upostgres
    This should output:
    You are connected to database "postgres" as user "postgres" on host "localhost" at port "5432"
  • This package will install PostgreSQL to $Env:ProgramFiles\PostgreSQL\[MajorVersion].
  • Silent install options.
  • If you have problems during installation see troubleshooting page.
  • If you didn't specify password during setup and didn't record the generated one, you need manually reset it using the following steps:
    • Open file data\pg_hba.conf in PostgreSql installation directory
    • Change METHOD to trust and restart service with Restart-Service postgresql*
    • Execute "alter user postgres with password '[my password]';" | psql -Upostgres
    • Revert back data\pg_hba.conf to METHOD md5 and restart service

Virtual package

Each major version has its own package: postgresql12, postgresql11, postgresql10, postgresql9.

Virtual package postgresql also contains all versions that depend on adequate major version, but using it without problems require some special choco parameters.

To propagate package parameters to dependencies use --params-global choco install parameter with virtual package postgresql. Assuming latest version is 12, to provide password the following two examples result in identical installation:

cinst postgresql --params '/Password:test' --params-global
cinst postgresql12 --params '/Password:test'

To uninstall dependent package use --force-dependencies:

# The following two examples are identical
cuninst postgresql --force-dependencies
cuninst postgresql12 postgresql

# This example uninstalls only postgresql virtual package and not postgresql12
cuninst postgresql

To force reinstallation via virtual package use --force-dependencies:

# The following two examples are identical
cinst postgresql --force --force-dependencies
cinst postgresql12 --force --force-dependencies

# This will reinstall only postgresql virtual package and not its dependency postgresql12
cinst postgresql -force

# This one is different then the first one as vcredist140 dependency is not reinstalled
cinst postgresql12 --force

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
