[bug#37855] [PATCH] gnu: guix-data-service: Enable build time tests.

[Christopher Baines]

Previously the tests were not run, as PostgreSQL wasn't running at build
time. Now there's a new target, check-with-tmp-database that uses ephemeralpg
to run the tests without relying on an externally managed PostgreSQL service.

* gnu/packages/web.scm (guix-data-service)[arguments]: Remove #:tests? #f, and
set #:test-target to "check-with-tmp-database".
[native-inputs]: Add ephemeralpg.

Nice, LGTM!

I wonder: can’t you just have “make check” do this, or do you want to
have “make check” talk to a real database instead?

(For the Guix test suite, ‘test-env’ spawns a daemon with a temporary
store for test purposes; I wonder if the situation is comparable here.)

Thanks,
Ludo’.

Great, I've pushed this now as 353f5f7aa7ea575f9f04d3a0b277bbb8012b942d.

It's mostly a new target as I already had "make check" just run the
tests, but yeah, it might be more useful for "make check" to setup an
empty database, then run the tests. I'm not quite sure yet.
