Is it possible to use the same catalog for multiple connectors?

[hungtcs]

The reason is that I have linked multiple postgres databases,
and each postgres database actually has only one public schema.
When cross-database joint query, I have to write a very long table path, like this

select * from catalog_1.public.some_table 
  left join catalog_2.public.some_table on ...
  left join catalog_3.public.some_table on ...

It would be great if there is a way to link different connectors to the schema under the same catalog.
