Logical replication support for TRUNCATE Update the built-in logical replication system to make use of the previously added logical decoding for TRUNCATE support. Add the required truncate callback to pgoutput and a new logical replication protocol message.
Publications get a new attribute to determine whether to replicate truncate actions. When updating a publication via pg_dump from an older version, this is not set, thus preserving the previous behavior.
