As far as I'm aware, the full snapshot doesn't normally exist in shared memory, hence the need for publication of some sort. We could dedicate a shared memory region for publication but then you have to decide how many slots to allocate, and any number you pick will be too many for some people and not enough for others, not to mention that shared memory is a fairly precious resource. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
