In general, I find that the Pg docs pretty clear state what is ANSI 
standard and what isn't within Pg. You can also view the ANSI-92 
standard here:

In terms of making sure you're cross platform compatible, I'd say you 
have to designate a series of platforms (e.g. MySQL 5, Pg 8.3, Oracle 
X, MS SQL X, ext) which you will test against and explicitly support. 
You will find that no matter how tightly you attempt to build your 
platform against ANSI-92 (or any other std) if you do not regularly 
test against a set of platforms, your solution will converge on 
supporting only the platforms you do regular test against.

I hope that helps,
