You have got to admire the evil villany we're up against. Buying the 'M' in LAMP and then exploiting that position. Business first, not the heart and minds of developers. Luckily the 'L' + 'A' + 'P' cannot be bought. LAPP stack anyone?
If you're going the "non-default" route of using postgresql you might as well ditch PHP. Unless P=Python? :-) LAMP is a loaded acronym which these days basically means "a web app built using FOS but not in Java or Ruby".
Am I normal?
