Hmm. I set up what I believe to be the same test case you were using,
and it's not crashing for me. In fact, with the latest code, I
haven't been able to produce any error at all. When I reverted my
last commit, I managed to get this:
ERROR: could not open relation with OID 18229
STATEMENT: select current_setting('port') port, count(*) from t
...but just once, and with no other error messages. So I'm either
missing a step somewhere, or something about your system just happens
to tickle this moreso than on mine.
