Hi @dtroiano , I also have same problem.
In my environment,
confluent version : 6.0.9
debezium-connector-postgresql version: 2.2.1
I am sure I do the same as you mentioned, but the connector is unavailable.
And if I install debezium-connector-postgresql version: 1.9.7, then it works.
steps that I executed:
export CONFLUENT_HOME=~/Downloads/confluent-7.5.2
bin/confluent local services start
bin/confluent-hub install debezium/debezium-connector-postgresql:latest
bin/confluent local services connect stop
bin/confluent local services connect start
Could you please help me to check?
