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.
