> This is exhibited by the following SqlValidatorTest:
> {code:java}
> sql("SELECT COALESCE(NULL, ROW(1))")
> .withValidatorConfig(c -> c.withCallRewrite(false))
> .type("RecordType(RecordType(INTEGER EXPR$0) EXPR$0) NOT NULL");
> {code}
> The program is rejected with:
> From line 1, column 8 to line 1, column 29: Parameters must be of the same
> type
> The sad thing is that I already fixed a similar issue in [CALCITE-7195], but
> my fix was insufficient.
