pg_get_multixact_members

Returns the transaction ID and lock mode for each member of the specified multixact ID. The lock modes forupd, fornokeyupd, sh, and keysh correspond to the row-level locks FOR UPDATE, FOR NO KEY UPDATE, FOR SHARE, and FOR KEY SHARE, respectively, as described in Section 13.3.2. Two additional modes are specific to multixacts: nokeyupd, used by updates that do not modify key columns, and upd, used by updates or deletes that modify key columns.

English manual coverage begins with PostgreSQL 7.1. Source history and runtime observations have their own recorded version boundaries.
