At a glance the JDBC patch doesn't use it on the send path, but presumably clients could use this when sending binary-format arrays to the server - but only if the server understood the format. (Ideally a pair of settings would be useful here - one to say "the server understands the new format" and another the client sets to say "please use the new format" that defaults to off - then you could avoid confusing old clients, too) Oliver -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
