Use Debian PHP version for pgsql package

[93jun]

Summary

Use the Debian PHP version selected by geerlingguy.php when building the default PostgreSQL extension package name.

Details

The role depends on geerlingguy.php, which sets php_default_version_debian per distribution release. The php-pgsql role currently defaults Debian-family systems to php8.3-pgsql unconditionally.

On Ubuntu 22.04, geerlingguy.php installs/configures PHP 8.1, but this role then tries to install php8.3-pgsql, which is not available from the default package repositories.

This change makes the default Debian package follow the selected PHP version:

php{{ php_default_version_debian }}-pgsql

Validation

• Reproduced the Ubuntu 22.04 failure with the current default:

  No package matching 'php8.3-pgsql' is available
  

• Re-ran the same Ubuntu 22.04 role path after this change with php_enable_webserver: false for a minimal container, and the play completed successfully:

  failed=0
  

• Ran git diff --check.

• Parsed vars/Debian.yml as YAML successfully.
