39f69bc38f Start updating for the v7.0 release. 
Use "generic functions" for math and other routines.
Use SQL92 "type 'literal'" syntax rather than Postgres "'literal'::type".

1763a7c1ea Tweak GROUP BY so that it will still accept result-column names, but only 
after trying to resolve the item as an input-column name.  This allows us
to be compliant with the SQL92 spec for queries that fall within the spec,
while still accepting the same out-of-spec queries as 6.5 did.  You'll only
lose if there is an output column name that is the same as an input
column name, but doesn't refer to the same value.  7.0 will interpret
such a GROUP BY spec differently than 6.5 did.  No way around that, because
6.5 was clearly not spec compliant.

dd979f66be Redesign DISTINCT ON as discussed in pgsql-sql 1/25/00: syntax is now 
SELECT DISTINCT ON (expr [, expr ...]) targetlist ...
and there is a check to make sure that the user didn't specify an ORDER BY
that's incompatible with the DISTINCT operation.
Reimplement nodeUnique and nodeGroup to use the proper datatype-specific
equality function for each column being compared --- they used to do
bitwise comparisons or convert the data to text strings and strcmp().
(To add insult to injury, they'd look up the conversion functions once
for each tuple...)  Parse/plan representation of DISTINCT is now a list
of SortClause nodes.
initdb forced by querytree change...
