Summary

PostgreSQL is an object-relational database management system

Description

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.

Features

Package parameters

  • /AllowRemote - Allow remote connections with username and password from all hosts by adding appropriate lines in the pg_hba.conf
  • /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.
  • /Port - Server port, if not set it defaults to 5432 or the first available port after it.
  • /NoPath - Do not add PostgreSql bin directory to the PATH.

Other parameters could be set via --ia argument, for example, to set custom components:

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

See Silent install options for details.

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:

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
