I considered writing a PAM module to do some stuff at one time (to try
to solve the two-passwords-for-a-user problem), but the non-intrinsic
complexity to perform pretty simple tasks in the whole thing is pretty
terrible -- it ended up being more attractive to do fairly ugly role
mangling in Postgres's own authentication system. And, like you, I
don't know of any serious competition to PAM in performing simple
authentication delegations.
