Hi, It seems postgres cache the plan under CacheMemoryContext during the plpgsql executing. If there is a function with lots of variables and every one of them got a default value, postgres will allocate lots of memory for caching the default value plan(we have to run the function at least once). Once we DROP the function, the memory consumed by the plan will be leak. The same thing for the compiled function structure(PLpgSQL_function).
Is this an oldest known question? Thanks, Tao Ma -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
