Fujii Masao 92913fc290 Avoid using ambiguous word "non-negative" in error messages.
The error messages using the word "non-negative" are confusing
because it's ambiguous about whether it accepts zero or not.
This commit improves those error messages by replacing it with
less ambiguous word like "greater than zero" or
"greater than or equal to zero".

Also this commit added the note about the word "non-negative" to
the error message style guide, to help writing the new error messages.

When postgres_fdw option fetch_size was set to zero, previously
the error message "fetch_size requires a non-negative integer value"
was reported. This error message was outright buggy. Therefore
back-patch to all supported versions where such buggy error message
could be thrown.

Test extensions and libraries
=============================

src/test/modules contains PostgreSQL extensions that are primarily or entirely
intended for testing PostgreSQL and/or to serve as example code. The extensions
here aren't intended to be installed in a production server and aren't suitable
for "real work".

Furthermore, while you can do "make install" and "make installcheck" in
this directory or its children, it is NOT ADVISABLE to do so with a server
containing valuable data.  Some of these tests may have undesirable
side-effects on roles or other global objects within the tested server.
"make installcheck-world" at the top level does not recurse into this
directory.

Most extensions have their own pg_regress tests or isolationtester specs. Some
are also used by tests elsewhere in the tree.

If you're adding new hooks or other functionality exposed as C-level API this
is where to add the tests for it.
