I would like to reformat all of our SQL to have a concise coding style. This makes it far easier to understand the code for a casual contributor, and lets us spot errors more easily. Most importantly, it makes it much easier to grep (search) the code because it is more likely to be in the same syntax Some key changes: * SQL keywords are always UPPERCASE, e.g. `SELECT WHEN AS END ...` * types, variables, aliases, and field names (identifiers) are always lower case * `LANGUAGE 'plpgsql'` is now `LANGUAGE plpgsql` (no quotes) * a few minor spacing/semicolon cleanups P.S. Per @TomPohys request, `TABLE` is spelled using upper case despite being a type for consistency with PG Docs. Same for `LANGUAGE SQL` vs `LANGUAGE plpgsql`.
