The BDR code has recently started using security labels as a place to store table-specific data. That widens its use a fair bit ... and most likely, other extensions will also start using them as soon as they realize that it can be used for stuff other than actual security labels. (FWIW we shouldn't have called these "security labels" but just generically "labels" or something like that.) -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
