PFA the patch with above updates.
Thanks for updating the patch! I like this feature.
I tested this feature and encountered two issues:
Issue 1: Error with pg_get_process_memory_contexts()
When I used pg_get_process_memory_contexts() on the PID of a backend process
that had just caused an error but hadn’t rolled back yet,
the following error occurred:
Session 1 (PID=70011):
=# begin;
=# select 1/0;
ERROR: division by zero
Session 2:
=# select * from pg_get_process_memory_contexts(70011, false);
Session 1 terminated with:
ERROR: ResourceOwnerEnlarge called after release started
FATAL: terminating connection because protocol synchronization was lost
Issue 2: Segmentation Fault
When I ran pg_get_process_memory_contexts() every 0.1 seconds using
\watch command while running "make -j 4 installcheck-world",
I encountered a segmentation fault:
LOG: client backend (PID 97975) was terminated by signal 11: Segmentation
fault: 11
DETAIL: Failed process was running: select infinite_recurse();
LOG: terminating any other active server processes
