Added simple task to enter db console

[jwoertink]

Fixes #516

This task just calls psql passing in your configured DB URL. I have no idea how to test this 😂

I want to make this task precompiled, but I need to test that locally first to see if it works.

🤨 ok.... what?

but how?

[jwoertink]

Ok, it turns out that if you pre-compile the db tasks, then change the db settings, the pre-compiled tasks will use the old settings, and not the new changes. Lame 😒 ...For now we can't precompile this, but it would be amazing if we could figure out how to precompile all of those.
