If the connection is "busy", that means that the asynchronous query is still busy receiving a result from the server. Once it is no longer busy, a result has arrived and is ready to be consumed. You have to consume the result before you can send the next query. Yours, Laurenz Albe -- Cybertec | https://www.cybertec-postgresql.com
