Thanks for reporting. I've added this item to the PG11 open items list in: https://wiki.postgresql.org/wiki/PostgreSQL_11_Open_Items#Open_Issues I've placed it there so that it does not get forgotten about. It's still to be decided if we can come up with something low-risk enough that will resolve the issue. -- David Rowley http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
