I thought maybe the pg_ident.conf file was enough to simply say
"connections from www-data should be considered as coming from user
moseley" and then sameuser would work (i.e. www-data would be able to
connect to moseley's databases).

BTW -- when using a map like this that uses the ident service, what dsn
string is used when connecting?  (I'm using Perl, BTW.)

You mean adding a "local" entry too?

host    all         all         127.0.0.1         255.255.255.255   ident testmap
local   all         all                                             ident testmap

bumby:/etc/postgresql$ psql newdb
psql: FATAL:  user "www-data" does not exist
bumby:/etc/postgresql$ psql -Umoseley newdb
psql: FATAL:  IDENT authentication failed for user "moseley"
bumby:/etc/postgresql$ psql -Uwww-data newdb
psql: FATAL:  user "www-data" does not exist

This is why I ended up creating a new database user with a password and then
granting access to ALL of my objects to the new database user.  And then
using that username/password in the connect string in the web
application.

Can I turn on debugging in Postgresql to see why it's failing?  That
would likely help resolve the problem.
