pg_qualstats13 - A PostgreSQL extension collecting statistics about predicates
- Description:
pg_qualstats is a PostgreSQL extension keeping statistics on
predicates found in WHERE statements and JOIN clauses.
This is useful if you want to be able to analyze what are
the most-often executed quals (predicates) on your database.
The powa project makes use of this to provide index
suggestions.
It also allows you to identify correlated columns, by
identifying which columns are most frequently queried
together.
