I think we might need to step-back to basic design of this feature
since this patch seems to have unhandled corner cases that are
difficult to find.
I've written out the basic design below and attached
corresponding patch.
I'm starting to study how this feature behaves. At first, when I executed
the following query, the function never returned. ISTM that since
the autovacuum launcher cannot respond to the request of memory
contexts dump, the function keeps waiting infinity. Is this a bug?
Probably we should exclude non-backend proceses from the target
processes to dump? Sorry if this was already discussed.
SELECT pg_get_backend_memory_contexts(pid) FROM pg_stat_activity;
