There are quite a few benefits to this approach:
- Reduce config duplication
- The two sql_exporter configs were super similar with just a few
differences
- Pull SQL queries into standalone files
- That means we could run a SQL formatter on the file in the future
- It also means access to syntax highlighting
- In the future, run different queries for different PG versions
- This is relevant because right now, we have queries that are failing
on PG 17 due to catalog updates
