PR Summary

• Introduced TestEnvironment class
  Added a new file TestEnvironment.php in the tests/Support/ directory, with methods to retrieve PostgreSQL host and port. This centralizes the access to these values.

• Modified CommandTest.php
  Using the new TestEnvironment class to retrieve PostgreSQL host and port for DSN instantiation and assertions in the testShowDatabases() method.

• Modified PDODriverTest.php
  Using the new TestEnvironment class to retrieve PostgreSQL host and port for driver instantiation in the testConnectionCharset() method.

• Modified TestTrait.php
  Using the new TestEnvironment class to retrieve PostgreSQL host and port in the methods getConnection, getDb, and getDsn. This refactoring centralizes the way these values are used across multiple methods.

Usage two container for tests (PHP and DB) in one network. In this case I need change host to actual.

This is not a problem with the package, it is a problem with your configuration.

It's package problem that deny change host address.

Imagine that each user, make a pr to adapt the package to its configuration, for me it should look like this, simple configuration.
