It should ERROR on a logical slot, since it has no way of correctly advancing the catalog_xmin or finding a reasonable restart_lsn for logical decoding. I'm still fine with the name, since I plan to add that capability in pg11 by running through logical decoding and ReorderBufferSkip()ing each xact until we reach the target lsn. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
