Call Function::eraseFromParent() when codegen fails
Description
I tried disabling codegen but it's the same.
Postgresql and Oracle say the first query below should evaluate to true.
[localhost.localdomain:21000] > select 'a' = cast('a' as char(2));
Query: select 'a' = cast('a' as char(2))
+----------------------------+
| 'a' = cast('a' as char(2)) |
+----------------------------+
| false |
+----------------------------+
Fetched 1 row(s) in 0.02s
[localhost.localdomain:21000] > select 'a' = cast('a' as char(1));
Query: select 'a' = cast('a' as char(1))
+----------------------------+
| 'a' = cast('a' as char(1)) |
+----------------------------+
| true |
+----------------------------+
Fetched 1 row(s) in 0.01s
[localhost.localdomain:21000] > select cast('a' as char(2));
Query: select cast('a' as char(2))

+----------------------+
| a |
+----------------------+
Fetched 1 row(s) in 0.01s
[localhost.localdomain:21000] > select length(cast('a' as char(2)));

+------------------------------+
| 1 |

Postgresql
