i would be content if the API allowed me to pass it a plain-text password,
and that was compared against pg_shadow, where the password is stored
encrypted.

at this point in time, i do not see a method of doing that without my mods
or using external password files.

if the API as above existed, then i would be happy to see "password" go away
(although it should be depreciated to a --enable option, otherwise you are
going to ruin a bunch of existing code).

it would be nice (in my opinion) if you could have multiple (cascade) entries
in pg_hba.conf.

and a flag in pg_shadow to "appoint" a blessed scheme.

ie. if a user identd's ok, and the identd flag is set in pg_shadow, then
it is ok.  otherwise, move on to the next pg_hba.conf entry.

the reasoning for this is that i (and i assume others) have two classes of
access.  some type of authenticated client/user and scripts.

hardcoding passwords in scripts is just wrong.

i sometimes have "localhost" set up on ident, and non-localhost on some
type of passord/crypt type thing.  but i don't want to allow all local users
access via ident.

i recognize that some of this can be done with the ident mapping facility,
but again, that is an external file, and thus presents management issues.
