Out of the box, PostgreSQL lacks static code analysis at compile time like ORACLE can do.
plpgsql_check provides this capability (and a profiler), but needs to be called manually. So I tried to emulate ORACLE's behavior with an event trigger.
The plpgsql_compile_check extension is experimental. You MUST preload plpgsql and plpgsql_check with shared_preload_libraries='plpgsql,plpgsql_check' in postgresql.conf, otherwise strange things happen!
