Add support for the apache and community editions of timescaledb in the hypertable generator.

Resolves #12

@sebastian-ederer, can you lend a hand with these last few failing tests?

[sebastian-ederer]

@anton-schieber Of course, I'll have a look at it tomorrow.

@anton-schieber I fixed all tests and resolved the issues.

I had to update the expected SQL for one test, but all other tests failed because of this:

In WrapCommunityFeatures() the SQL for statements were just being appended. However, PL/pgSQL doesn't allow bare SELECT statements that return data - they must either use PERFORM or EXECUTE. I chose EXECUTE, because PERFORM also has some limitations and EXECUTE was made for dynamic SQL (see stackoverflow).

I also changed the RAISE WARNING because I think the enterprise edition is the one from TigerData and Apache Edition would be more fitting. Please correct me if that was wrong, but looking at the code this seemed logical to me.

// Before
sb.AppendLine("        RAISE WARNING 'Skipping Community Edition features (compression, chunk skipping) - not available in Enterprise Edition';");

// After
sb.AppendLine("        RAISE WARNING 'Skipping Community Edition features (compression, chunk skipping) - not available in Apache Edition';");

P.S. I've abused your branch for a small refactoring to use explicit types instead of var where I forgot to change it, lol.

LGTM

Awesome, thanks for that
Could you tag a new release? Gonna do some testing on the new stuff today

[sebastian-ederer]

Yes, I just started the pipeline. Wait for a few minutes then it should've run through. Maybe it takes another couple of minutes until NuGet indexes the new version
