For a long time, postgres had a lot of issues that made it less
suitable for high web environments, especially 24x7 high load. vacuum
was a nightmare, transaction overhead was very high, and the complex
disk format made upgrades a real pain (only this last issue remains).
The postgresql optimizer has always had an edge, but it wasn't so cut
and dry back then. It was only with the 8.x versions that postgres
really started pulling away.
