I have some patches for version 6.5 (postgresql.snapshot.tar.gz dated Mar 26):

varchar-array.patch	this patch adds support for arrays of char() and
			varchar(), which where always missing from postgres,
			and also fixes a bug in the catalog definition of
			array_in(). You can now define filds as:

				x  char(12)[],
				y  varchar(9)[],

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 other than 8192.
			The patch also replaces all the occurrences of `8192'
			and `1<<13' in the sources with the proper constants
			defined in various include files.

			I found a little problem with this patch: flex defines
			an internal buffer size of 16K which is obviously
			inadequate with large queries. I solved the problem
			replacing 16K with 64K with sed, but this introduces
			some constants hardwired in the Makefiles, which I
			don't like very much. I don't even know if this fix
			is portable with other versions of flex. If someone
			has a better idea it is welcome.

In the .tgz attachment there are also two sql file I used for testing.
