qt4-mac and postgres sql driver

[Michael Dickens]

Hi Petr - I see no reason to not include variants for psql[83,84,90,91]; certainly makes sense if some of the older ones do not do +universal correctly but the newer ones do.  I'll add those to the 4.7.0 Portfile I'm working on right now & will be checking in either later today or tomorrow depending on how quickly testing goes.

I think it would be awesome to have sub-variants for what you want to do: I specify +psql=84 or +psql=90, which internally to the Portfile I have a single "variant psql" and then inside a "switch psql_val" with cases, or whatever keywords / phrasing one decides to use.  That way, I can always know that the user wants some +psql variant (the default if no "=foo" is added), and then allow relatively simple upgrading to newer versions -- even simply based on the user's command line entry (as I would do in this case).

Anyway, thanks for the tip, and look for an updated qt4-mac soon. - MLD
