> With this patch, we don't want to copy over the table properties or any other
> physical properties (storage handler e.t.c) of the source table when CREATE
> TABLE LIKE TABLE command is executed. Only table schema (logical properties)
> should be copied. This implementation is consistent with other SQL engines
> like Mysql, Redshift etc.
