> For resolved metadata we should omit foreign keys that reference tables that are filtered out.
> For example with
> CREATE FOREIGN TABLE G1(g1e1 integer, g1e2 varchar, PRIMARY KEY(g1e1, g1e2));
> CREATE FOREIGN TABLE G2( g2e1 integer, g2e2 varchar, PRIMARY KEY(g2e1, g2e2), FOREIGN KEY (g2e1, g2e2) REFERENCES G1));
> and a filter to only include G2, we should omit the foreign key so that the returned ddl is valid.
