As discussed in #15, the Schema configuration parameter doesn't
actually do anything, and we realized that it's possible to support this
feature by using an alternate configuration for pgxpool in search_path.

Here, drop Schema and add a test that verifies that this technique
works. So as to not have to create and migrate an alternate schema, we
cheat a little bit by repointing the schema and then just verifying that
we can't find a river_job table there.

I'm finding the test hierarchy in client_test.go to be pretty
confusing in determining on what best practice is for what should go
where, so I'm starting out with a new Test_Client which I'm hoping we
can start using as a base for most of the general tests in here in a
more reusable way. I leverage JobArgsReflectKind and WorkFunc in its
subtests so that it's not dependent on our various global job args that
are defined all over the place. Instead, args and the work routine are
colocated right inside the test.

Configuring an alternate schema is definitely going to need its own
documentation page somewhere because it's not obvious, but that'll come
separately.

Fixes #15.

Sorry for the spam, but renamed this since we renamed Run -> Start.

Same idea here. Run -> Start.

Started a new branch of client tests because it's not clear what should go where in here anymore, and I'm trying to put in something where new tests can be added without starting a fresh test every time. We'll try to take advantage of JobArgsReflectKind and WorkFunc in subtests so that args and work definition can be colocated right inside the test rather than being floating around in global state somewhere.

StartInsertAndWork below is a basic client test (not related to the Schema change) added to show roughly what this look like.

Nicely done, I like the new test pattern. If nothing else, inline worker definitions are great for concise & easy to follow tests.

As discussed in #15, the `Schema` configuration parameter doesn't
actually do anything, and we realized that it's possible to support this
feature by using an alternate configuration for pgxpool in `search_path`.

Here, drop `Schema` and add a test that verifies that this technique
works. So as to not have to create and migrate an alternate schema, we
cheat a little bit by repointing the schema and then just verifying that
we can't find a `river_job` table there.
