I've been looking at a fix for this, and I think I have it. The solution
looks to be to redefine off_t to 64-bit (the standard headers *always*
define it as 32-bit, and there is no way to change that - at least not
that I can find).
I have the fix made for just bin/pg_dump for now (in pg_dump.h), and I'm
testing that. (So far only on MSVC builds)
A question though - is there any *gain* from using 64-bit offsets in the
actual backend? The change could of course be done in port.h, but that
will affect the whole backend (and require a few more functions than
just fseeko/ftello to be redefined) which could have larger
So - provided that this works after my test is completed, is the better
place to do this for just pg_dump/pg_restore, or attempt to do it for
the whole backend?
