I will update commitFest with the latest patch immediately after sending the mail.
OK, done setting the status to ready for committer.
We already have two different versions of make_absolute_path() in the tree - one in src/backend/utils/init/miscinit.c and one in src/test/regress/pg_regress.c.
I don't think we need a third one.
If we put it in port/ like this patch done, then we should make the other callers use it. We might need one for frontend and one for backend (I haven't looked into that much detail), but definitely the one between pg_regress and pg_ctl should be shared.
