The current TODO list has: Dependency Checking =================== * Flush cached query plans when the dependent objects change, when the cardinality of parameters changes dramatically, or when new ANALYZE statistics are available A more complex solution would be to save multiple plans for different cardinality and use the appropriate plan based on the EXECUTE values. * Track dependencies in function bodies and recompile/invalidate This is particularly important for references to temporary tables in PL/PgSQL because PL/PgSQL caches query plans. The only workaround in PL/PgSQL is to use EXECUTE. One complexity is that a function might itself drop and recreate dependent tables, causing it to invalidate its own query plan.
