CVE-2026-6638 — LOW severity vulnerability | Release Alert

**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 - See the [Feature Matrix](https://www.postgresql.org/about/featurematrix) ## 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: ```powershell choco install postgresql13 --params '/Password:test /Port:5433' --ia '--enable-components server,commandlinetools' ``` Check all [installer](https://www.enterprisedb.com/downloads/postgres-postgresql-downloads) 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](https://wiki.postgresql.org/wiki/Troubleshooting_Installation). - 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](https://community.chocolatey.org/packages/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: ```sh choco install postgresql --params '/Password:test' --params-global choco install postgresql12 --params '/Password:test' ``` To uninstall dependent package use `--force-dependencies`: ```sh # 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`: ```sh # 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](https://github.com/mkevenaar/chocolatey-packages/issues) that the package is no longer updating correctly.
