generated twice. But for some subqueries, generating code off of the same
tree twice causes problems. So now MULTI-INDEX OR makes a copy of the

anything at all rather than creating a tombstone function. In this way,
function deletes that happen inside virtual-table destructors that are run

Lexer and grammar rules for a RETURNING clause on DELETE/INSERT/UPDATE.

Actually making this work, though, will involve a lot more code which will
likely slow down processing for the common case where there is no
RETURNING clause. Furthermore, RETURNING seems to be of limited usefulness
and it is not standard SQL. So we abandon it here. These experimental
changes are parked in a branch as an historical reference. If circumstances
changes, we might take up the cause again some day.

yy_reduce() subroutine and into the main parser routine, so that when overflow
is detected, it can exit immediately. This saves a single conditional in
the main loop of the parser.

Change the unions of the Table.addColOffset field from characters to bytes.
...
This makes the query that implements ALTER TABLE ADD COLUMN more complex and
slightly slower, but also makes CREATE TABLE statement parsing faster by
avoiding a call to sqlite3UtfCharLen(). Since, CREATE TABLE parsing is far
more common than ALTER TABLE, this is a net win for performance.

later columns are constrained by an IN operator and the earlier index columns
limit the search to a small number of rows. Use the new OP_SeekScan opcode

in order to guard against pathological cases where the estimated number
of rows to be scanned is far too small.

it doesn't find a match quickly enough. For this work-in-progress check-in,
OP_SeekScan is still a no-op and OP_SeekGE still ends up doing all the work.

further into WHERE clause processing.
