I'm new to PostgreSQL and see that there are 3 versions in the Ports and 
bsd.mk.ports defaults to 7.4 to resolve pgsql dependencies.
I yahood/msnd/googled a lot but couldn't find a comprehensive comparison 
regarding features/performance. There are severaly MySQL comparisions but 
that aren't of interest any more since that's what I've been using before.

So please can one explain me in short words what the main featrue difference 
is between 7.4, 8.1, 8.2? (I found out that 7.4 and 8.2 are incompatible 
regarding php5-pgsql conjunction)
And what are the main performace differences (for a very small site) between 
7.4, 8.1 and 8.2?
If it's not obvious (with the above answered), why are there 3 stable 

Thanks a lot in advance,
