**Hello,

Steps to reproduce:

1. Install Template DB Postgresql - settings according to doc's

Result:

      **      Template seems to work but

       zabbix trigger returns problem: "PostgreSQL is not running on hostname1"

          Expression:

<7 

ps -ef |grep [p]ostgres

postgres 9110 1 0 Nov04 ? 00:00:03 /usr/pgsql-11/bin/postgres -D /opt/postgresql/data
postgres 9111 9110 0 Nov04 ? 00:01:12 postgres: startup recovering 00000001000000000000006B

postgres 9114 9110 0 Nov04 ? 00:00:03 postgres: stats collector
postgres 9115 9110 0 Nov04 ? 00:07:40 postgres: walreceiver streaming 0/6BC56E40

ps -ef |grep [p]ostmaster

no rows returned.

Trying to change Trigger Expression to: 

<7

Cause Error: Cannot update trigger

• Incorrect item key "proc.num[*postgres*]" provided for trigger expression on "hostname1".
  Expected:

according to database documentation: "postmaster is a deprecated alias of postgres."

https://www.postgresql.org/docs/11/app-postmaster.html

How may i change this trigger/item or solve this problem?
