Notification only fires once.

Expected behavior

Notification is received each time a row is added.

Actual behavior

I get the first notification, then nothing.

Steps to reproduce

Uses the example code under 'robust listeners' connected to the my notification. If I run the listen blah command in phAdmin4 I get the correct notification each time.

Environment

Version of pg-promise: 10.5.8
OS type (Linux/Windows/Mac): Linux (WSL2 on ubuntu 20.04)

Then nothing when the next row is inserted.
