'master' file

Commit mods to regress.sh so that split out tests are run...look forward
to finding out how to do a proper redirect to continue visual cleanup :)

sure exactly what it is it fixes...

psql now returns error from queries and errors files, so ignore return code.

Also, I think that an extra source of noise in the diff of regress.out and
expected.out is caused by not substituting the shared library file
extension in the regression.input file (much like the paths and the
usernames are sub'ed). This seems to be fixed with the following patches
to regression.input and the Makefile... If I'm off base here, please tell!
