pg_hba.conf settings for postgres

[Teju Jakkidi vlogs <teja.jakkidi05@xxxxxxxxx>]

Hello Admins,

I have below settings in my pg_hba.conf file:

local   all             postgres                                trust
local   all             all                                     md5
host    all             all             127.0.0.1/32            trust
host    all             all             0.0.0.0/0               md5
host    all             all             ::1/128                 trust

host    all             all             ::/0                    md5

Our expectation is that - when logging as postgres user from local host, it should not prompt for the password as we have local for postgres set to trust and loopback is set to trust.

However, when running psql as postgres user from the local host, it is still asking for the password.

Adding below lines in  pg_hba.conf file is working as expected:

host     all           postgres       Local IP/32            trust

Adding an entry for local host IP and making it trust for postgres user is working as expected and not prompting for password. However, removing this line is prompting for the postgres password from the local host.

Not sure why there needs to be an entry for IP even when we already have local for postgres and loopback set to trust.

Any inputs here will be of great help!!

Thanks,

Teja.
