selecting from a pseudo-table like table_partitions with a dot-prefixed name causes assertion error

To reproduce

Repro test:

 @Test
    public void testPseudoTableErrorOut() throws Exception {
        assertMemoryLeak(() -> {
            execute("create table \"a.b\" (ts timestamp);");
            assertPlanNoLeakCheck("select table_partitions('a.b');", "abc");
        });
    }

Expected behaviour:

It is a pseudo table so should not be selected as a column. But it is allowed, if the table name has no ., it will return a record column filled with nulls.

Additional context

No response

Start with the provided testPseudoTableErrorOut reproduction and trace how the pseudo-table name is resolved when it contains a dot. Run the reproduction against the existing query-planning tests, then verify that the dotted pseudo-table produces the expected error while the non-dotted case retains its documented behavior.
