Thanks for your comments. I'll fix it later.

BTW, I have a question which community (PostgreSQL or SELinux) shall
eventually maintain the module, although PostgreSQL provides a set of
interfaces for access control modules?
I thought SELinux side (mainly I and NEC) will maintain the sepgsql
module being suitable for the interfaces.

If we need another proof-of-concept module independent from selinux
for regression test, at least, it is not a tough work.

Thanks,
