Queries without schema specification fail to fully push down in DuckDB

[kysshsy]

What happens?

Create two foreign tables in different schemas, one in tpch and one in public. Queries that don't specify a schema will fail to fully push down to DuckDB.

To Reproduce

This issue is unrelated to specific data.

pg_lakehouse=# create schema tpch;
CREATE SCHEMA
pg_lakehouse=# CREATE FOREIGN TABLE tpch.t1 (
    boolean_col       boolean,
        int8_col          smallint,
        int16_col         smallint,
        int32_col         integer,
        int64_col         bigint,
