feat(debug): enhance SQL debugging

[benjie]

When using DEBUG="graphile-build-pg:sql", SQL will now be output formatted, with the the various __local_#__ entries colour coded. We also no-longer prepend graphile-build-pg:sql to every line in the SQL statement. This makes debugging a lot easier!

Before:

After:

GraphQL Query

query {
  allPeople(first: 3, offset: 1) {
    nodes {
      nodeId
      id
      name
      email
      createdAt
      postsByAuthorId(orderBy:PRIMARY_KEY_DESC, first:1) {
        nodes {
          nodeId
          id
          headline
          body
          author: personByAuthorId {
            nodeId
            id
            name
          }
        }
      }
    }
  }
}
