Mysql is OK if you don't really need a relational database -

Don't see why that would be a problem for postgresql either as long as

Even though I posted those performance benchmarks, I'd want to do some 
serious testing before trusting it.  I've had my share of problems with 
things based on Berkeley DB too, but perhaps those problems are fixed now.
