Someone probably changed or removed the "ident" authentication for 
localhost in pg_hba.conf.  Start there.  The default configuration is:

# "local" is for Unix domain socket connections only
local   all         all                               ident
# IPv4 local connections:
host    all         all         127.0.0.1/32          ident
# IPv6 local connections:
host    all         all         ::1/128               ident

If you don't think that's the case, post the output of the script so 
that we can tell what's prompting you.
