I don't think this will actually help --- if anything it exposes you
to the bug more :-(. Given my current theory, there is not anything
wrong with the init file. The problem is a sort of race condition
that would be triggered by very high cache-inval traffic during startup
of a new backend. I looked at the cache inval array in your coredump,
and it looked like there had been a whole bunch of table deletions
happening concurrently with the startup --- "whole bunch" meaning
hundreds if not thousands. Is there anything in your application
behavior that might encourage a lot of table drops to happen
concurrently?
I'll get you a real fix as soon as I can, but might not be till
tomorrow.
