n_live_tup and n_dead_tup are always 0 for "PostgreSQL Database estimates live/dead rows|"

[mcindea]

Hello,

I noticed in the Zabbix template pg.table.n_live_tup[{$PG_CONN},{#DATABASE}] and pg.table.n_dead_tup[{$PG_CONN},{#DATABASE}] and I tried using them to calculate the garbage ratio / DB.

The problem is that they are always returned 0. This works fine for the table ones, but after a bit of digging the query in the docs will never work, because relname will never equal {#DATABASE}.

Is there any other way to get the garbage ratio? I do have some other custom queries which I use and involve a join between pg_class and pg_stat_all_tables on oid=relid. But I preferred to use this module instead.

Thank you very much for your work
