Pavel,

I just dropped the extension, thats where I got the second error. 

Looks like when any plpgsql functions runs it us looking for plpgsql_check.

Try to remove it - it does not sense on the production server.

If I remove plpgsql_check getting below error

If I drop only the extension (plpgsql_check) getting below error

you should to remove plpgsql_check by DROP EXTENSION plpgsql_check (only this way). plpgsql_check is just language checker. Why it is called by your application?

Show plpgsql_check.mode  gives an error as unrecognized configuration parameter.

We use plprofiler 

it can be plprofiler issue, or maybe some problem when plpgsql_check is used with plprofiler together

can you execute following scenarios

1. uninstall plpgsql_check and check if you can get the exception

2. install plpgsql_check and uninstall plprofiler, and check the issue

3. try to install debug symbols and send to us stack trace.

Regards

Pavel

Pavel,

Plpgsql_check configured under postures 13 lib.

If it us not enabled default how can I do it?

Do you use profiler or tracer or passive mode from plpgsql_check?

What is result of "show plpgsql_check.mode" ?

Well, no --- it's the kernel reporting a segfault in plpgsql_check.

Although now that you mention it, there should also be traces of this
crash in the Postgres log; it would be interesting to see what's
reported there.

plpgsql_check can be used as a profiler or tracer too. But this functionality is not enabled by default.

So usually at runtime, the plpgsql_check is not active. So it can be nice to get plpgsql_check configuration and stack trace.

This is v13, so if I wrangled gdb correctly 350 is FuncCall.  (One
thing I'm wondering though is if the extension somehow got compiled
against wrong-version headers.  But you'd expect that it largely
wouldn't work at all if so.)

I did error in calculation, it is FuncCall

Pavel
