-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I can't tell you much about mysql, but I have been using postgresql for a few years now. On the last project I was on, we were using postgres to handle a database that grew by more than 1GB/day (I don't recall how many millions of rows that represented), and we were able to tune it to get the performance we needed on pretty standard servers. It supports transactions, triggers, stored procedures, subqueries, and I have yet to come up with a join that it couldn't do (In my current project, we routinely use every sort of join except for a cross join to get our data out the way we like it). If you're doing anything the IPs or network addresses, it also has some sweet special data types and operators for them. As for an unbiased comparison between postgres & mysql, your best bet might be to talk to people who are good at one or the other and make your own comparison... Generally speaking, the people with the knowledge you seek are already fairly biased towards the one they use... --Nick -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) Comment: pgpenvelope 2.10.2 - http://pgpenvelope.sourceforge.net/ iD8DBQE+60MRv+hjYTGg7s4RAoosAJ9hZVUesEVUpNcVTPLoJVBrzgfptgCfeuG4 0qn+p8V24+JH82+fI05LexM= =h5vr -----END PGP SIGNATURE-----
