Hmm. AFAICS this should always be followed by an ERROR message. There
are at least two issues here: why does this message occur, and why does
a crash follow instead of more-graceful error recovery?
Does any additional information show up in the postmaster log?
Could you provide your test program? Could you provide a stack trace
from the backend core dump?
