I've moved discussion of this to pgsql-hackers, since this appears to be an actual bug. > Side note: while trying to debug this I've noticed, that the TOAST > chunks on 32-bit systems have the documented size of 2000 bytes, on > 64-bit systems they have 1996 bytes. Is this normal/on purpose? I don't have the exact numbers in my head, but the TOAST chunk size does depend on a MAXALIGN calculation, so it being different between 32- and 64-bit isn't surprising. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
