Right. pgTAP doesn't run tests, it's just a collection of assertion functions written in SQL and PL/pgSQL. It could
havebeen used via a forking Perl script that would connect to the proper boxes, run the tests, collect the results,
etc.But it clearly would have been a PITA, and the path of least resistance is often the best solution when hacking.
Goingwith dcheck, which already did what you wanted, was clearly the right choice.
Hopefully we can have the build farm animals run the dcheck target once SSI is committed.
Best,
