Allow parsing expressions with ") -" (scan.l, scan.c only).

Browse Source 
Make "TABLE" optional in "LOCK TABLE" command
 and "... INTO TABLE..." clause.
Explicitly parse CREATE SEQUENCE options to allow a negative integer
 as an argument; this is an artifact of unary minus handling in scan.l.
Add "PASSWORD" as an allowed column identifier.
These fixes will require a "make clean install" but not a dump/reload.
