That's way I was checking against another lib (ecpg.4) in my port to
differentiate between 73 and 74.

Maybe you should do the check like MySQL ( see _MYSQL_VER ) to prevent

I keep wondering if we shouldn't check first for the pkg-info and then
that the file actually exists or something like that. After all, we do
assume pkg information is correct.

:-) we need a way to protect us about this; it is possible that one
port will not work (or compile) with the wrong PGSQL version; but the
LIB check, as you say, won't yield this.

Well, I don't argue for the name of the knob, is its functionality that
I'm after :)

Yes, no argument here. I was just trying to be user friendly.
