Subject: BUG #17665: pg_stat_statements useless with variable number of parameters in IN close
Date: Thu, 27 Oct 2022 10:42:52 +0000
Message-ID: <17665-d10ccd445cd66f6c@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 17665
Logged by: Sebastien Caunes
Email address: bokanist@gmail.com
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 ?
