Agreed, though we can restrict that to a few things at first. * Zeroing pages, making pages all 1s * Transposing pages * Moving chunks of data sideways in a block * Flipping bits randomly * Flipping data endianness * Destroying particular catalog tables or structures etc As a contrib module, so we can be sure to never install it. ;-) -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
