PostgreSQL version: 10.1
Operating system:   CentOS 7
Description:

Hello!
I use PostgreSQL and check process in zabbix - proc.num[postgres]

But in CentOS 7 process for run posgresql is postmaster.

I download latest postgresql10-server-10.1-1PGDG.rhel7.x86_64.rpm and see
/usr/lib/systemd/system:

ExecStart=/usr/pgsql-10/bin/postmaster -D ${PGDATA}

But at

"postmaster is a deprecated alias of postgres."

If is not bug. I am sorry.
Thank you.

There are two reasons:

* Historical reasons: It has always been postmaster with the RPMs.
* Other reason: I personally find grepping postmaster easier than others :)
