Note: I have never tried this, but if I needed to I think I would
do something along these lines:
check out man postmaster and man pg_dump, then
I think I would try something like this:
/usr/local/pgsql7.0.3/bin/postmaster -i -p 5433 -D /usr/local/pgsql7.0.3/data &
/usr/local/pgsql7.0.3/bin/pg_dump -h localhost -p 5433 dbToDumpName > dumpFile
Notice that you should probably specify these path names absolutely
so that you can be sure you are getting the right ones.
I was doing it this way because I could not see from pg_dump's man page
how to get it to connect via socket to a different postmaster
(the -D switch seems to do something completely different there)
