Crystal reports works fairly well via ODBC. Erwin 3.x has some support
for postgresql, though it's not great if you write postgresql specific
stuff. My understanding is this has been improved in later versions of
erwin, though I've not tried them. FWIW all of these tools should work
on some level due to odbc (or perhaps jdbc) compatibility. The quality
of support though is probably less than that for oracle or sql server,
but it it's still likely they would be good enough to do the job.
