The pg_resetxlog -m option was changed from -m XID set next multitransaction ID
to -m XID,OLDEST set next multitransaction ID and oldest value but the man page does not reflect that change. It was introduced in 0ac5ad5134f2769ccbaefec73844f8504c4d6182 "Improve concurrency of foreign key locking", but there is also no explanation there. It is apparently needed in pg_upgrade. This should be documented, and I think the help line should be changed to something like -m XID,XID set next and oldest multitransaction ID -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
