In Postgresql template for Zabbix Agent 2 some Items use a macro named {$PG.CONNSTRING} that is not present in macro list, where I find a macro named {$PG.CONNSTRING.AGENT2} and items becomes "Not supported"

If you change all occurrence of {$PG.CONNSTRING} with {$PG.CONNSTRING.AGENT2} on set up a macro named {$PG.CONNSTRING} all works fine.
