tests to return the correct results per SQL9x when given NULL inputs.
Reimplement these tests as well as IS [NOT] NULL to have their own
expression node types, instead of depending on special functions.
From Joe Conway, with a little help from Tom Lane.

16-Mar-00: trailing + or - is not part of the operator unless the operator
also contains characters not present in SQL92-defined operators.  This
solves the 'X=-Y' problem without unduly constraining users' choice of
operator names --- in particular, no existing Postgres operator names
become invalid.

Also, remove processing of // comments, as agreed in the same thread.

Try to provide a more lucid discussion in 'Using Aggregate Functions'
tutorial section.

Move around a few other keywords which were not in the right category.
DEC and SESSION_USER are not yet committed to gram.y,
 since I'm in the middle of working on JOIN syntax too.

Clarify information on implicitly-typed constants.

Add more examples for language components.

lisp.sgml is a placeholder for Eric Marsden's upcoming contribution.
catalogs.sgml is not yet marked up or integrated.
 It should perhaps become an appendix.

Add id tags to chapter and section headings to ensure good labels
 on output html files.

Add date/time parsing procedure (perhaps should be in appendix).
Add time zone information (ditto).
Update keyword list.
