The "psql_sigint_callback" function is not defined under WIN32.

I've fixed a missing NULL argument in the section you pointed out, though.

I've used the shared infrastructure in pgbench.

I've noticed yet another instance of the cancelation stuff in
"src/bin/pg_dump/parallel.c", but it seems somehow different from the two
others, so I have not tried to used the shared version.
