postgresql-13-pg-qualstats - 2.0.2-2+b1 main

This extensions tracks WHERE clauses predicates and JOIN predicates.
Statistics will report whether the predicate was evaluated as an index scan or
not, how many time the expression appeared, how many times the operator was
executed and how filtering the expression is. If pg_stat_statements is
enabled, it can also track to which statements the predicate belongs.
