What is really disturbing about the ones testing the size functions is
that they may be costly when running installcheck. By the way, it would
be nice to avoid the system-wide REVOKE, which could impact any tests
running in parallel. You could simply check for some other NULL
values.

This gets better, thanks. I would suggest using a less realistic value
than "/tmp/", which could become a security hole if copy-pasted around...
