Template DB PostgreSQL - error connections

[maxxus]

Hi guys!
I have a problem setting up a template Template DB PostgreSQL.

For setting it I used manual:

https://www.zabbix.com/ru/integrations/postgresql

but, I received error:
error reason for "Zabbix server pgsql.ping.time["{$PG.HOST}","{$PG.PORT}","{$PG.USER}","{$PG.D B}"]" changed: Preprocessing failed for: 1.Time: 0.573 ms


At the same time, the command from the console is executed successfully:

zabbix_get -s 127.0.0.1 -k 'pgsql.transactions["127.0.0.1","5432","zbx_monitor","postgres"]'
{"idle":0,"active":0,"waiting":86407.439003,"pr epa red":0}

zabbix_get -s 127.0.0.1 -k 'pgsql.ping["127.0.0.1","5432","zbx_monitor","postgres"]'
127.0.0.1:5432 - принимает подключения (accept connections)










pg_hba.conf

host all zbx_monitor 127.0.0.1/32 trust
host all zbx_monitor 0.0.0.0/0 md5
host all zbx_monitor ::0/0 md5


System:
zabbix_server (Zabbix) 5.0.5
Debian 10.6 x64


Perhaps someone knows where to look for the error?
I'm already stumped
