we'll go over to disk-based sort if we reach that limit.
This fixes Stefan Kaltenbrunner's observation that sorting can suffer an
'invalid memory alloc request size' failure when sort_mem is set large
enough.  It's unfortunately not so easy to fix in 8.1 ...

Wouldn't it be better to use the UINT64CONST macro?  I realize this
file is Windows-only, but we do worry about more than one compiler
on that platform.

Patch against HEAD to add TRUNCATE to the list of commands that aquire

multiples of the page size (at least, that's how I interpret the
Darwin code).

corrections and documentation.

relations are still checked for permissions etc as soon as they are
opened.  The original form of the patch could hold exclusive lock for a
long time on relations that the user doesn't even have permissions to
access, let alone truncate.

checkpoint in the bgwriter.  This forestalls overflow of the fsync request
queue, which is not fatal but causes considerable performance degradation
when it occurs (because backends then have to do their own fsyncs).  Per
patch from Itagaki Takahiro, modified a little bit by me.

a need for it back in the neolithic era, but it's certainly dead code in
any PG release we would recognize as such.  Since it forces an additional
network round trip to the backend, getting rid of it should provide some
small performance improvement for large-object-using clients.

did not reject this, but now it does.

1) rank_cd now use weight of lexemes
2) rank_cd and rank can use any combination of normalization methods:
        no normalization
        normalization by log(length of document)
        -----/------- by length of document
        -----/------- by number of unique word in document
        -----/------- by log(number of unique word in document)
        -----/------- by number of covers (only rank_cd)

Improve cover's search.
