After updating zabbix-agent2 from 6.2.8 to 6.4.0, postgres database monitoring does not work.

Centos 7

zabbix-agent2

{$PG.URI}  tcp://localhost:5432

• Unknown metric pgsql.bgwriter

in logs agent

2023/03/18 12:18:51.626913 [1] cannot monitor metric "pgsql.db.bloating_tables["tcp://localhost:5432","zbx_monitor","password","db1_test"]": Unknown metric pgsql.db.bloating_tables

If you install version 6.2.8, then everything starts working.
