As part of the ALTER TABLE lock reductions we've now agreed that reloptions should have a lock level associated with them, so we can take appropriate lock levels.
Attached patch will be applied at start of 9.5 dev cycle, so that any new relopt authors are aware that lock levels are needed for any new work. Later patch will then use this infrastructure to (attempt) to reduce lock levels, assuming no problems. Added to next CF for June 2014, not for commit yet. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
