flinkcdc pgsql 部分表无法增量同步

我同时同步下面这些表时，其中两张表无法进行增量同步，是怎么回事呢？
"public.mes_db_hw_ny_station," +
"public.mes_db_ny_station," +
"public.mes_db_hw_station," +
"public.mes_db_station," +
"public.mes_zj_hw_station," +
"public.mes_zj_ny_station," +
"public.mes_zj_hw_ny_station," +
"public.mes_zj_station"

即使单独把两表拿出来同步，配置全量+增量模式，只执行全量不会进行增量，配置增量模式时，一直没有数据同步
