In addition to the documentation links people have already suggested, I'd
also suggest
http://andreas.scherbaum.la/blog/archives/282-table-size,-database-size.html
which gives some helpful suggestions on measuring the actual size of data
you've got in the database already. It's possible to make a mistake when
trying to compute overhead yourself; loading a subset of the data and
measuring the size is much less prone to error.

I can't imagine why the connection pooling links I suggested before
wouldn't work perfectly fine on a Mac. You're correct to first nail down
why PHP is connecting more than you expect, but eventually I suspect
you'll need to wander toward pooling.

You might want to give some specifics and ask about this on the pgAdmin
mailing list: http://www.pgadmin.org/support/list.php
OS X support is relatively recent for pgAdmin and I see some other recent
fixes for specific issues on that platform.
