The returned type of abs is error. #1335
Description
Describe the bug
In the pg database, the abs support varchar data type
But the result in the datafusion is
❯ select abs('123');
Plan("Coercion from [Utf8] to the signature Uniform(1, [Float64, Float32]) failed.")
❯
In other size, the returned type of abs is the input type.
If the input type is int, the returned type must be the int.
If the result data is out of range, PG will throw error message.
postgres=# SELECT abs(-2147483648);
ERROR: integer out of range
postgres=#
but in the datafusion, it convert the -2147483648 to INT64
❯ SELECT abs(-2147483648);
+-------------------------+
| abs(Int64(-2147483648)) |
+-------------------------+
| 2147483648 |
+-------------------------+
To Reproduce
execute the sql
❯ select abs('123');
Plan("Coercion from [Utf8] to the signature Uniform(1, [Float64, Float32]) failed.")
❯
Expected behavior
postgres=# select abs('123');
abs
-----
123
(1 row)
the result of type is always double
