0a6259f539 Remove the MySQL upsert syntax. As an optional alias to the insert table 
name in order to finish out PostgreSQL upsert syntax emulation.

6cd7d489db Update the upsert parsing so that it accepts conflict-target labels using 
the PostgreSQL syntax, and also accepts the MySQL "ON DUPLICATE KEY"
syntax.

2c2e844a36 More complete parsing of UPSERT, including UPSERT within a trigger. 
The sqlite3Insert() logic to actually perform the UPSERT is not yet
implemented, however.

41aab89b31 Faster keywordCode() implementation by taking advantage of the fact that

81eba73ebf Experimental changes toward "index only" tables. Add the ability to specify 
options on CREATE TABLE statements using the WITH clause modeled after
PostgreSQL and SQL Server.  Only the "omit_rowid" option is currently
recognized and that option is currently a no-op.
