I just tried with 8.4.1. Started with the default configuration, created
data/pg_ident.conf with:
pg_map root postgres
pg_map postgres postgres
Replaced in pg_hba.conf:
< local all all trust
by
> local all all ident map=pg_map
Restarted the server, and then:
$ su -
# /usr/local/pg84/bin/psql -U postgres
psql (8.4.1)
Type "help" for help.
postgres=#
... it appears to works.
Now if I remove that line in data/pg_ident.conf:
pg_map root postgres
and reload the server and retry, I get the expected rejection:
psql: FATAL: Ident authentication failed for user "postgres"
and in the server logs:
LOG: no match in usermap for user "postgres" authenticated as "root"
CONTEXT: usermap "pg_map"
FATAL: Ident authentication failed for user "postgres"
That's on ubuntu 9.04, with postgres compiled from source.

On unix systems, it's a standard recommendation not to run anything as root
when it's possible to do otherwise, so we just apply this to psql I guess.
