* Update a tuple. * * NB: do not call this directly unless you are prepared to deal with * concurrent-update conditions. Use simple_table_tuple_update instead. * * Input parameters: * relation - table to be modified (caller must hold suitable lock) * otid - TID of old tuple to be replaced * slot - newly constructed tuple data to store * cid - update command ID (used for visibility test,

 * for additional info.
