Actually, it's entirely possible to do stuff like web counters, you just want to do it differently in PostgreSQL. Simply insert into a table every time you have a hit, and then roll that data up periodically. And using MyISAM is no panacea, either. Trying to keep a web counter in a MyISAM table means you'll serialize every web page on that counter update. -- Jim C.
