Hello,

The '0002-Free-columns-data-as-well.patch' doesn't seem to be ok, since it
also tries to pkg_free the actual column values. PKG allocation like this
only happens for db_oracle, other modules rely on their libraries to
allocate the actual column name and to also free it. Thus, the column data
freeing should be placed in db_oracle_free_result .

The second patch is ok, as it's a good idea to completely reset the column
info after freeing them.

Regards,
Vlad
