When publishing changes through a artition root, we should use the row filter for the top-most ancestor. The relation may be added to multiple publications, using different ancestors, and 52e4f0cd47 handled this incorrectly. With c91f71b9dc we find the correct top-most ancestor, but the code tried to fetch the row filter from all publications, including those using a different ancestor etc. No row filter can be found for such publications, which was treated as replicating all rows. Similarly to c91f71b9dc, this seems to be a rare issue in practice. It requires multiple publications including the same partitioned relation, through different ancestors. Fixed by only passing publications containing the top-most ancestor to pgoutput_row_filter_init(), so that treating a missing row filter as replicating all rows is correct.
