85712da90d Mike Ansley's fixes for long queries. This change just 
corrects flex myinput() routine so that it doesn't assume there is only
one bufferload of data.  We still have the issue of getting rid of
YY_USES_REJECT so that the scanner can cope with tokens larger than its
initial buffer size.

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.

cb7cbc16fa Hi, here are the patches to enhance existing MB handling. This time 
I have implemented a framework of encoding translation between the
backend and the frontend. Also I have added a new variable setting
command:

SET CLIENT_ENCODING TO 'encoding';

Other features include:
	Latin1 support more 8 bit cleaness

See doc/README.mb for more details. Note that the pacthes are
against May 30 snapshot.

d4a95fd7ab Allow more variations on valid floating point numbers (e.g. ".1", "1e6"). 
Reintroduce fixes for unary minus parsing with leading spaces.

31b9e3fc68 Temporarily back out fixes for unary minus parsing. 
Will re-introduce for v6.4 but requires fixes for automatic type
 conversion beforehand.

561aead3f1 Allow parsing expressions with ") -" (scan.l, scan.c only). 
Make "TABLE" optional in "LOCK TABLE" command
 and "... INTO TABLE..." clause.
Explicitly parse CREATE SEQUENCE options to allow a negative integer
 as an argument; this is an artifact of unary minus handling in scan.l.
Add "PASSWORD" as an allowed column identifier.
These fixes will require a "make clean install" but not a dump/reload.
