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(.., .., ..)"
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 It's Postgres 11.5. I will look into links you shared. Regards, AD.
