Key word table update for SQL:2008 - Mailing list pgsql-docs

I was planning to update the key words table
(http://developer.postgresql.org/pgdocs/postgres/sql-keywords-appendix.html)
for SQL:2008 and was wondering whether there is interest in keeping the
SQL-92 through SQL:2003 columns.  It might look a bit overloaded then.

Comments?
