a -D<datadir> option

Pointed out by: afc@teri.superlink.net

but it gets rid of the temptation to modify the old source files :)

regress.sh modified to get rid of queries.sql tests, as they are
performed vis sql/*.sql

Its starting to actually take shape and look as expected...

partially split

The whole file needs updating, but will work on that after finishing
with the splits

user-friendly (and more useful)

'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 :)

tests allows us to have a 'for...done' loop inside of regress.sh for
both doing the tests, and determining fail/ok results

FreeBSD

The Makefile(s) have all been cleaned up such that there is a single
LDFLAGS vs LD_ADD or LDADD or LDFLAGS or LDFLAGS_BE.  The Makefile(s)
should be alot more straightforward then they were before...and
consistent

don't accidentally use non-GNU make.

sure exactly what it is it fixes...

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