We have received reports that when using "PostgreSQL by Zabbix agent 2" with PostgreSQL in a stopped, a continuous memory consumption akin to a memory leak has been observed.

Reported to have consumed about 2GB of memory over the course of approximately 2-3 weeks (Version 6.0.9).

After testing for 1-2 days with Agent 2 version 6.0.17, with the PostgreSQL service stopped,
We were able to replicate a continuous increase in memory from the PID of "zabbix-agent2-plugin-postgresql".

There is a possibility of a memory leak with postgresql plugin here that needs to be investigated in more detail.
