.pgpass not working ( centos7, pgagent_96 )

[JaeWon Lee <thejaewon@xxxxxxxxx>]

Hi,  .pgpass seems to be not working.

Could you check my pgagent setting?

OS : centos 7   ( I did not disable selinux )

Database : postgresql 9.6.5
pgagent : pgagent_96 3.4.0-9.rhel7  ( installed package using  yum )

1. I logged on centos server as user 'frank'

2. Before starting pgagent, I checked status of pgagent.  ( I did not enable pgagent_96 service. )
[frank@web]$ systemctl status pgagent_96.service
● pgagent_96.service - PgAgent for PostgreSQL 9.6
   Loaded: loaded (/usr/lib/systemd/system/pgagent_96.service; disabled; vendor preset: disabled)
   Active: inactive (dead)

3. I started pgagent. At first it looks successful. But after tens of seconds, it failed to create connection and died.

( While starting CentOs asked me frank's OS password. )

[frank@web]$ systemctl start pgagent_96.service
[frank@web]$ systemctl status pgagent_96.service

4. I checked pgagent log.

( Log in /var/log/pgagent_96.log )

5. Checked my .pgpass file. ( .pgpass is in frank's home directory. /home/frank )
[frank@web]$ ls -alZ .pgpass
-rw-------. frank frank unconfined_u:object_r:user_home_t:s0 .pgpass
[frank@web]$ ls -al .pgpass
-rw-------. 1 frank frank 43 16 Oct 16:23 .pgpass
[frank@web]$ id -Z
unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
[frank@web]$ id
uid=1000(frank) gid=1000(frank) groups=1000(frank),10(wheel) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

6. Checked my pg_hba.conf.
[frank@web]$ su - postgres

-bash-4.2$ pwd
/var/lib/pgsql/9.6/data
-bash-4.2$ ls -alZ pg_hba.conf

-rw-------. postgres postgres unconfined_u:object_r:postgresql_db_t:s0 pg_hba.conf( pg_hba.conf )

( pg_hba.conf )

#host    replication     postgres        ::1/128                 ident

7. I changed postgres user's password like this.

postgres=# ALTER USER postgres WITH PASSWORD 'pwd';

These are all I did. I can't guess what I should do. Help me please...
