Review Comment:
This is very tricky place, if my approach is correct seems i need to fill
appropriate comment here.
I think this is calcite related bug, but due to incorrect behavior with
binary types it can`t be reproduced without calcite core code changes, after
similar to
[IgniteTypeCoercion](https://github.com/apache/ignite-3/pull/5145/files#diff-e321e723c2ee035a28656a0ed73aff3429b5ea855934cdfb8e51dd7c91157f03)
fix, related code (i think bug is inside)
RelBuilder#setOp ->
...
RelDataType rowType = getTypeFactory()
.leastRestrictive(inputTypes);
and as a result will be called padding:
org.apache.calcite.rex.RexBuilder#makeLiteral
case BINARY:
return makeBinaryLiteral(
padRight((ByteString) value, type.getPrecision()));
fast reproducers :
1. comment this code and run: test_blob_function.test
2. the same - comment and check result for
```
sql("CREATE TABLE blobs (b varbinary);");
sql("INSERT INTO blobs VALUES (x'aa'::binary), (x'bbcc')");
List<List<Object>> res = sql("SELECT OCTET_LENGTH(b) FROM blobs
ORDER BY 1");
```
