I am working on a system which will be heavily dependent on functions
(some SQL, some PL/pgSQL). I am worried about the backend caching query
execution plans for long running connections.
Given:
- Processes which are connected to the database for long periods of time
(transactions are always short).
- These processes will use some functions to query data.
- Lots of data is being inserted into tables that these functions query.
- Vacuums are done frequently.
Am I at risk of degrading performance after some time due to stale
execution plans?
Thanks,
-Kelly
