Well, we need to find out what's causing that. There are two possible
sources of that error (one elog in src/backend/access/nbtree/nbtinsert.c,
and one in src/backend/access/nbtree/nbtpage.c) and neither of them
should ever fire.
If you want to track it yourself, please change those elog(ERROR)s to
elog(PANIC) so that they'll generate core dumps, then build with
--enable-debug if you didn't already (--enable-cassert would be good too)
and get a debugger stack trace from the core dump.
Otherwise, can you extract a test case that causes this without needing
vast resources to run?
