Hi Justin,
Thanks for your response.
I suspect JDBC is using parameterized queries (postgres $1, $2, ..) and psql
isn't (unless you type "prepare p AS SELECT ..." and execute p(.., .., ..)"
isn't (unless you type "prepare p AS SELECT ..." and execute p(.., .., ..)"
Yes JDBC is using parameterized queries which get constructed dynamically depending upon user privileges in the application.Does this cause any issues?
I don't know what server version you have, so I don't know whether to suggest
testing with plan_cache_mode=force_custom_plan
testing with plan_cache_mode=force_custom_plan
It's Postgres 11.5.
I will look into links you shared.
Regards,
AD.
