text
action list used during the subscription process. At the time a subscriber copies over data from the origin, it sees all tables in a state somewhere between two SYNC events. Therefore this list must contains all log_actionseqs that are visible at that time, whose operations have therefore already been included in the data copied at the time the initial data copy is done. Those actions may therefore be filtered out of the first SYNC done after subscribing.
