PostgreSQL version: 15.0
Operating system: all
Description:
Not really a bug, but this issue makes pg_stat_statements almost useless.
One of my customer have queries with variables number of parameters in IN
closes
SELECT * FROM my_table WHERE id IN ($1, $2, $3, $4, ...) -- number of
parameters varies from one to thousands
And some queries have more than one IN close. This bloat the
pg_stat_statement table with all different version of the same query.
I think the parameters in IN close should be merged as one.
By the way, where should I submit this kind of improvement request ?
