feat(PostgreSQL): ✨ Postgress connection string feature for local and server connection string

This feature is based on this [issue](https://github.com/Fabio286/antares/issues/193)  I tested with the following posgress connection strings postgresql://postgres:pgpassword@127.0.0.1:5432/my_local_databse?connection=local postgres://serveruser:serverpass@test.db.elephantsql.com/my_remote_databse?connection=server  postgres://serveruser:serverpass@test.db.elephantsql.com:5432/my_remote_databse postgresql://postgres:pgpassword@127.0.0.1:5432/my_local_databse.

The connection string decoder is loaded before "test-connection", "check-connection", and "connect"
