Hi, hackers
I just wrote a test code for the `pg_buffercache` extension which
doesn't not have test code.
I wrote the sql query to ensure that the buffer cache results are the
same when `make installcheck` is performed.

Seems to be there now, at least:

https://commitfest.postgresql.org/38/3674/

However, I don't think we should have a 'target version' set for this
(and in particular it shouldn't be 15). I'd suggest removing that.

Thanks,

Stephen

Pushed with minor adjustments. Some notes:

* A .gitignore file is needed so that "git status" won't whine after
running the test. This tends to be pretty much boilerplate; I copied
it from another contrib directory.

* Pay attention to "git diff --check" formatting warnings. In this
case it bleated about an extra blank line at the end of the .sql file.

* I didn't care for the direct use of pg_show_all_settings(). The
official API there is the pg_settings view, and there's no need for
this test to get friendly with the view's internals.

Thanks for the patch!

Is there any reason we don't add a .gitignore in the contrib/
directory to ignore all */log/, */results/ and */tmp_check/ by
default rather having at least /log/, /results/ and /tmp_check/ in
almost all subdirectories .gitignore? Sure any underlying
"(log|results|tmp_check)" top-directory will then be ignored even if
it's not supposed to be needed, but I don't think it would matter in
practice. And if it does matter you could still force some file to be
included or even override the parent gitignore.

Re: pg_buffercache: add sql test

I've been missing what I have to add to the .gitignore file when I
write the test.
I will refer to it when I write the test code from now on.

Thank you.
