I've tried to rerun the 'archie' benchmark with the current patch, and
once again I got
  PANIC:  could not split GIN page, didn't fit

I reran it with '--enable-cassert' and with that I got

TRAP: FailedAssertion("!(ginCompareItemPointers(&items[i - 1],                  &items[i]) < 0)", File:
"gindatapage.c",Line: 149)
 
LOG:  server process (PID 5364) was terminated by signal 6: Aborted
DETAIL:  Failed process was running: INSERT INTO messages ...

so the assert in GinDataLeafPageGetUncompressed fails for some reason.

I can easily reproduce it, but my knowledge in this area is rather
limited so I'm not entirely sure what to look for.
