Subject: alignment errors on decstation5000 running ultrix 4.2
To: postgres@postgres.berkeley.edu
Sender: pg_adm@postgres.berkeley.edu

Hi,

postgres 3.1 on a decstation5000/200 running ultrix 4.2 is puking
CONSTANTLY with unaligned access errors. Is there some -D option I can
recompile with to get rid of the problem? Here is a sample error
message; judging from the pc's logged, we are in a tight loop somewhere.
Needless to say, the performance of the backend on this platform is less
than abysmal.

Cheers,
			-- Sean
