fix(users/Profpatsch/whatcd-resolver): SQL formatting off

It turns out the pg_format thing is just too slow for my use-cases
most of the time, even when pooling the mf. Most queries stay 90%+ in
the perl script, even though they are very fast to execute on their
own, screwing up the traces a lot.

So instead I replace the `postgres-simple` quasi-quoter that strips
whitespace (and tends to screw up queries anyway) with a simple one
that just removes the outer indentation up to the first line.

Why did I spend so much time on pg_format haha
