   I'm receiving a similar error:
   
   ```
   Exception has occurred: OperationalError
   IO: [libpq] ReadHeader failed: Expected PGCOPY signature of 11 bytes at 
beginning of stream but found -1 bytes of input
   OSError: [libpq] ReadHeader failed: Expected PGCOPY signature of 11 bytes at 
beginning of stream but found -1 bytes of input
   ```
   Where can view the logs to help me determine if there's someone wrong on my 
end?
   
   Adding a `LIMIT 10_000` to the end of my query fixes the issue, so either 
it's a data size problem or there's some bad data in a later record.
