If I have the Postgresql server installed on my machine i.e I have all the bins, libs and share directories of the Postgresql and I have the libs and sql's installed for one of the contrib extensions lets say "chkpass", how does one go about testing this extension exhaustively on the server? I ask this because I would want to do this manually first and then go about automating the testing of this extension. So rather than just execute CREATE EXTENSION and DROP EXTENSION I want some solid evidence that the extension is working fine under all circumstances and is not crashing the server at any moment? Looking for some new strategies and ideas to come my way through this.
