Moving on to the I/O routine changes. There was a little bit of
noise in the diffs, like one more comment removed that should still be
around. Indentation has needed some adjustment as well, there was one
funny diff with a cast to pgoff_t. And done this part as a first
step, because that's already a nice cut.

Then, about the test module.

src/test/modules/Makefile was missing, and once updated I have noticed
the extra REGRESS in the module's Makefile that made the tests fail
because we just have a TAP test. This also meant that TAP_TESTS = 1
was also missing from the Makefile. I've fixed these myself as per
the attached.

Anyway, I agree with the point about the restriction with WIN32: there
can be advantages in being able to run that in other places. I think
that we should add a new value for PG_TEST_EXTRA and execute the test
based on that, or on small machines with little disk space (think
small SD cards), this is going to blow up.

Also, is there a point in making that a TAP test? A SQL test should
work OK based on the set of SQL functions introduced for the file
creation step and the validation steps. We could also use alternate
outputs if required.
