+"""pg_listener.py.
+
+An ansible-rulebook event source plugin for reading events from
+pg_pub_sub
+
+Arguments:
+---------
+    dsn: The connection string/dsn for Postgres
+    channels: The list of channels to listen
+
+Example:
+-------
+    - ansible.eda.pg_listener:
+        dsn: "host=localhost port=5432 dbname=mydb"
+        channels:
+          - my_events
+          - my_alerts
+
+Chunking:
+---------
+   This is just informational a user doesn't have to do anything
+   special to enablo chunking. The sender which is the pg_notify
+   action from ansible rulebook will decide if chunking needs to
+   happen based on the size of the payload.
+   If the messages are over 7KB the sender will chunk the messages
+   into separate payloads with each payload having having the following
+   keys
+   * _message_chunked_uuid   The unique message uuid
+   * _message_chunk_count    The number of chunks for the message
+   * _message_chunk_sequence The sequence of the current chunk
+   * _chunk                  The actual chunk
+   * _message_length         The total length of the message
+   * _message_xx_hash        A hash for the entire message
+
+   The pg_listener source will assemble the chunks and once all the
+   chunks have been received it will deliver the entire payload to the
+   rulebook engine. Before the payload is delivered we validated that the entire
+   message has been received by validate its computed hash.
