Not sure if it's useful here, but a few months ago I prepared patches to
remove the config-auth option of pg_regress, which struck me as more
than odd, and replace it with a perl module. I didn't get around to
finishing them, but the patches as of then are attached.
I agree that having some switch that says "run everything with TCP" or
"run (almost) everything with Unix sockets" would be good.
