When synchronizing sequences for logical replication, a publisher-side permission failure could be reported as if the sequence were missing on the publisher, making the real cause harder to identify. This happened because pg_get_sequence_data() returns a row of NULL values when the replication connection lacks permission to read a sequence. Sequence synchronization treated that the same as a missing sequence, causing it to emit a misleading "missing sequence on publisher" warning. Fix this by distinguishing permission failures from genuinely missing sequences. The synchronization query now checks whether the replication connection has the required privilege for each published sequence, allowing the worker to report permission failures separately.
