Read all the docs at www.postgresql.org
Read the sections on administration. Postgresql is much more powerful
than MySQL, but with that greater power comes greater responsibility (i.e.
postgresql will NOT just run without some kind of daily maintenance
scheduled to keep it happy)
Read the sections on how to tune your queries and such.

Postgresql in general has a fairly good implementation of SQL92. The only
feature that I can think of that is ANSI SQL that MySQL has that
postgresql doesn't (yet) is "alter table drop column".
There are tons of little featurettes that MySQL has that you won't find in
Postgresql, but these are NOT ANSI SQL, but extensions that MySQL only
has.
My last advice is to look at other people's code, you'll find a lot of it
out there, at places like devshed and phpbuilder.
