'ident' is the default authentication type for local domain socket
connections, and it means that user 'x' can only connect as postgresql
role 'x'.

A web app likely runs as httpd or webuser or some such, so ident
authentication isn't really applicable.

You control the authentication methods in the pg_hba.conf file.   I'd
suggest doing this...

1) set (and remember) passwords for all roles, including the "postgres"
default adminstrator role....

     ALTER ROLE postgres WITH PASSWORD 'somepassword';

2) configure pg_hba.conf as follows...

     local        all postgres                 ident
     local        all all                           md5

     host        all all   127.0.0.1/32    md5
     host        all all  (yoursubnet)     md5

and HUP the master postgres process (pg_ctl ... reload).

this way, the postgres user can authenticate locally with ident, but all
other users will require passwords.
