somewhat OT - firebird vs postgres, and php support

Hi, I have just learnt about the firebird project and was wondering how alive it is. I know this is hard to quantify, but is development going better worse than postgres? I quite frankly don't like mysql that much and defintely want something like one of these two, but the simple fact of the matter is that I heard of postgres a long time ago, and firebird only today. Does that mean I have my head in a dark, smelly place, or that firebird is not as active? Will there still be people developing firebird in 10yrs? At a quick glance php support looks to be at least as strong for firebird, but a lot of things seem to be for interbase - are they always going to be compatible? I see pear db has support for interbase, does that mean firebird too, or just the latest interbase? Cheers Antoine -- G System, The Evolving GUniverse - http://www.g-system.at
