If the same user id + database combinations might be valid in both cases
(from both PHP and manual connections) I think your only other option
for distinguishing which auth method to use is to make them come in on
different addresses. Can you set up a secondary IP interface that only
the PHP server uses, for example?
There's no provision for saying "try this auth method, but if it fails,
try subsequent hba lines". It might be interesting to have that,
particularly for methods like ident that don't involve any client
interaction. (Otherwise, you're assuming that the client can cope
with multiple challenges, which seems like a large assumption.)
I don't have much of a feeling for how hard it would be to do in the
server.
