> While fetching partition metadata using partition filters, we use the column type of the table directly. However, char/varchar types can contain extra information such as length of the char/varchar column and hence it skips fetching partition metadata due to this extra information.
> Solution: Use the basename of the column type while deciding on whether partition pruning can be done on the partitioned column.
