It's a very light-weight alternative of memcmp the byte data, but there is still the same issue -- we might have different compressed results if we use different algorithm for TOASTing. So, it would be better to apply the present patch as-is. We can improve the comparison logic over the patch in another development cycle if possible. -- Itagaki Takahiro -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
