* For UPDATE and DELETE, use OP_DeferredSeek always. If the seek must laterdrh2020-08-14

This obviates the need for the WHERE_SEEK_TABLE and WHERE_SEEK_UNIQ_TABLE flags to sqlite3WhereBegin() and the ensuing complication, and it allows the covering index optimization to be used further into WHERE clause processing.
