surrounded by parentheses (but not all are meaningful).
Remove unused keywords ACL, APPEND, MERGE.
Requires a "make clean" to recompile all code since keyword numeric
 assignments have changed with keyword removal.

Cleanup for vacuum help, manual page, and error message

related to grammar and parser issues, with one postmaster fix.

Add lock to i386 asm.

with supporting code.

Creates SubLink node in gram.y.

psql.c patch for newatttypmod field.

varchar length.

Cleans up code so attlen is always length.

Removed varchar() hack added earlier.

Will fix bug in selecting varchar() fields, and varchar() can be
variable length.

Change NOTICE/NOTICE/NOTICE/WARN elog messages to a single message
 with a few newline/tab breaks embedded in the string. Much cleaner I hope.

 and from SELECT ... INTO ... support code.
Allow NOT, IS NULL, IS NOT NULL in constraints.
Define unionall boolean flag in SubSelect structure.
Implement row descriptors: (a, b, c) = (x, y, z).
Change IS TRUE, IS FALSE, etc. to expressions using "=" rather than
 function calls to istrue() or isfalse() to allow optimization.
Force type for TRUE and FALSE to bool.

 Formerly allowed only single arguments.
Declare column constraints using the usual list mechanism rather
 than explicit itemized lists.
Remove NOTNULL from default clause syntax (retain "NOT NULL").
 NOTNULL is not SQL92; eventually remove it from expressions too?
Move ISNULL, NOTNULL to Postgres-specific token declarations.
Fix up tabs and indenting on new CREATE USER commands.

Implement PRIMARY KEY and UNIQUE clauses using indices.

An extension to the code to allow for a pg_password authentication database
that is *seperate* from the system password file

Change elog WARN to NOTICE for unimplemented constraints.

 to NOTICE messages so that execution proceeds rather than halting.
 These clauses are ignored as stated in the messages.
Allow NOT NULL UNIQUE syntax (both were allowed individually before).
Allow Postgres-style casting ("::") of non-constants.

Support SQL92 syntax for type coersion of strings (type 'typeval').
 Example: "DATETIME 'now'". This works only for string constants and can
 not replace the CAST and ::type syntax which behave identically in this
 context.
