Describe the bug

Referencing a column from a certain form of select and order by clauses causes an error saying "projections require unique expression names".

To Reproduce

> create table foo as values (1, 2), (3, 4), (5, 6);
0 row(s) fetched.
Elapsed 0.002 seconds.

> select cast(column1 as text) from foo order by column1;
Error during planning: Projections require unique expression names but the expression "CAST(foo.column1 AS Utf8)" at position 0 and "foo.column1" at position 1 have the same name. Consider aliasing ("AS") one of them.
