These are all reasons why you'll do fine with MySQL if you're stuck with it, but they don't give a compelling reason to choose MySQL over e.g. PostgreSQL.

One thing I like about MySQL is the support available from third parties like Percona - I'll also recommend the book "High Performance MySQL", which gives some great details on performance tuning and query optimizing.

I'm not familiar with the offers for PostgreSQL - I'd like to hear what support services and books people with PostgreSQL experience would recommend.

For support, peruse the list for your continent at:

http://www.postgresql.org/support/professional_support/

For books, among the most important is Greg Smith's "PostgreSQL 9.0 High Peformance", but really, just search Amazon for "PostgreSQL" and browse the titles until you find one that matches your needs.

Personally, I've been working with postgres for a decade now. Most of what I've needed, I've just gotten from searching a/o asking on the mailing lists.
