Description

PostgreSQL is a powerful, open-source object-relational database management system (ORDBMS), developed at the University of California, Berkeley. It extends the POSTGRES project and pioneered features later adopted by other commercial systems.

PostgreSQL is free to use, modify, and distribute for private, commercial, or academic purposes.

Features

Package parameters

Parameter Description
/AllowRemote Enables remote connections (adds entries to pg_hba.conf).
/Password Sets password for postgres user. If omitted, one is generated. Ignored if PostgreSQL already exists.
/Port Database server port. Defaults to 5432 or next available port.
/NoPath Prevents adding PostgreSQL bin directory to PATH.

Other parameters could be set via --ia argument, example:

choco install postgresql13 --params '/Password:test /Port:5433' --ia '--enable-components server,commandlinetools'

Check all installer options by adding --help as command line argument.

Notes

  • 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].
  • 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: postgresql<Version>

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:

choco install postgresql --params '/Password:test' --params-global
choco install postgresql12 --params '/Password:test'

To uninstall dependent package use --force-dependencies:

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

# This example uninstalls only postgresql virtual package and not postgresql12
choco uninstall postgresql

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

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

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

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

Please Note: This is an automatically updated package. If you find it is out of date by more than a day or two, please contact the maintainer(s) and let them know here that the package is no longer updating correctly.
