Due to its size, in the Windows environment we can't dump this
database in any format except plain text, so the zlib issues don't
apply here.

I can believe that pg_dump faces the similar situtation, i.e., running
out
of kernel buffers. But seems pg_dump supports "-Z 0..9" option which
uses
some external I/O functions from zlib. This part may be not easy to
"retry".
