You mean the full-page write consistency tool? Heikki initiated that, a common interface to be able to mask pages and make them consistent for comparison on the master and the standby was also part of the deal. Another tool that we had better IMO put some efforts in porting into core is sqlsmith, which would actually be a complete rewrite because the upstream code is under GPL license and depends on libpqxx. -- Michael -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
