Function table_tuple_delete

src/include/access/tableam.h:1691–1699

* Delete a tuple. * * NB: do not call this directly unless prepared to deal with * concurrent-update conditions. Use simple_table_tuple_delete instead. * * Input parameters: * relation - table to be modified (caller must hold suitable lock) * tid - TID of tuple to be deleted * cid - delete command ID (used for visibility test, and stored into * cmax if successful) * crosscheck - if not

 * struct TM_FailureData for additional info.
