There is apparently something wrong with the JIT stuff in EDB's 12.2
build for macOS.  At least, that's the conclusion I came to after
off-list discussion with the submitter of bug #16264, which has pretty
much exactly this symptom (especially if you're seeing "signal 9"
reports in the postmaster log).  For him, either disabling JIT or
reverting to 12.1 made it go away.
