Tables information tab reports 'table not found' with new PostgreSQL extension 'pg_stat_monitor'

User impact:
User cannot view PG Tables in QAN

STR:
Add Percona PG to monitoring with pg_stat_monitor as query source
Open QAN and check PG Tables

Actual result:
Tables return either "Table not found: sql: no rows in result set" or "No table info from example nor explain"

Expected result:
Should work as with pg_stat_statements
