I agree to only fix them on HEAD. I merged this patch and the one in [1] as they are similar problems. Please see the attached patch. I removed the changes in tablesync.c which simplified the query in fetch_remote_table_info(), because it only works for publishers of v16. Those changes are based on pg_get_publication_tables() returning all columns when no column list is specified, but publishers of v15 return NULL in that case.
