8d21a6ef51 Keep long non-quoted numeric strings *as* untyped strings if they fail 
the obvious conversion.
Define a new pattern "decimal" which is non-exponential floating point
 for use with numeric() and decimal() types.

210055ad61 here are some patches for 6.5.0 which I already submitted but have never 
been applied. The patches are in the .tar.gz attachment at the end:

varchar-array.patch     this patch adds support for arrays of bpchar() and
                        varchar(), which where always missing from postgres.

                        These datatypes can be used to replace the _char4,
                        _char8, etc., which were dropped some time ago.

block-size.patch        this patch fixes many errors in the parser and other
                        program which happen with very large query statements
                        (> 8K) when using a page size larger than 8192.

                        This patch is needed if you want to submit queries
                        larger than 8K. Postgres supports tuples up to 32K
                        but you can't insert them because you can't submit
                        queries larger than 8K. My patch fixes this problem.

                        The patch also replaces all the occurrences of `8192'
                        and `1<<13' in the sources with the proper constants
                        defined in include files. You should now never find
                        8192 hardwired in C code, just to make code clearer.

99f61dac7e Defend against 'update oid'. Someday we might want to support 
that, but it'd be a New Feature, wouldn't it ... in the meantime,
avoiding a backend crash seems worthwhile.

a58843b49a Fix problems seen when result of a subselect was used in an 
expression context (ie, not at the top level of a WHERE clause).  Examples
like this one work now:
SELECT name, value FROM t1 as touter WHERE
(value/(SELECT AVG(value) FROM t1 WHERE name = touter.name)) > 0.75;

2deef968f4 After transforming a CASE expr with a default argument, 
delete the default argument from the node.  This prevents the executor
from spitting up on the untransformed argument expression.  Typical
failure was:
select (case f1 when 'val' then 'subst' else f1 end) from t1;

d13fe29000 I have a problem with Access97 not working properly when entering new 
records using a sub form, i.e. entering a new order/orderlines or master
and
detail tables.  The problem is caused by a SQL statement that Access97
makes
involving NULL.  The syntax that fails is "column_name" = NULL.  The
following attachment was provided by -Jose'-.  It contains a very small
enhancement to gram.y that will allow Access97 to work properly with sub
forms.  Can this enhancement be added to release 6.5?

 <<gram.patch>>
Thanks, Michael

Ok. I made patches replacing all of "#if FALSE" or "#if 0" to "#ifdef
NOT_USED" for current. I have tested these patches in that the
postgres binaries are identical.
