Hi,
We are running Postgresql 9.4 with streaming replication and repmgr. Operating system is RHEL6.8
On the master I can see multiple postmaster processes from the same data directory.
ps -ef |grep -i postgres|grep postm
postgres 81440 1 0 Jan31 ? 00:11:37 /usr/pgsql-9.4/bin/postmaster -D /var/lib/pgsql/9.4/data
postgres 97072 81440 0 12:17 ? 00:00:00 /usr/pgsql-9.4/bin/postmaster -D /var/lib/pgsql/9.4/data
postgres 97074 81440 0 12:17 ? 00:00:00 /usr/pgsql-9.4/bin/postmaster -D /var/lib/pgsql/9.4/data
The streaming replication with one standby looks fine.
I was expecting to see only one postmaster process instead of three and the time shown in PS output for two extra processes changes to current time with every PS command I enter. Secondly, I logfile is full of "Incomplete startup packet" message.
I need help from you experts, Is this the right behaviour of postgres? what could have gone wrong in my case.
Best Regards
Vikas
