Can I ask why it doesn't return the same snapshot ID each time? Surely it can't change since you can only export the snapshot of a serializable or repeatable read transaction? A "SELECT count(pg_export_snapshot()) FROM generate_series(1,10000000);" would quickly bork the pg_snapshots directory which any user can run. -- Thom Brown Twitter: @darkixion IRC (freenode): dark_ixion Registered Linux user: #516935 EnterpriseDB UK: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
