Title: Connection pool exhausting on bind error

I just happened to be on 'fix this shit up' mood so I also fixed this issue.

Invalid parameter passed to `PooledConnection.execute` method would previously invalidly cause connection pool to be exhausted.

The solution is to catch this error and propagate it directly back to the user.
