     * > An operator class with optional parameters can be specified for each column of an index.
     * The operator class identifies the operators to be used by the index for that column.
     * For example, a B-tree index on four-byte integers would use the int4_ops class;
     * this operator class includes comparison functions for four-byte integers.
     * In practice the default operator class for the column's data type is usually sufficient.
     * The main point of having operator classes is that for some data types, there could be more than one meaningful ordering.
     * For example, we might want to sort a complex-number data type either by absolute value or by real part.
     * We could do this by defining two operator classes for the data type and then selecting the proper class when creating an index.
     * More information about operator classes check:
     *
     * ### Useful links
     * https://www.postgresql.org/docs/current/sql-createindex.html
     *
     * https://www.postgresql.org/docs/current/indexes-opclass.html
     *
     * https://www.postgresql.org/docs/current/xindex.html
     *
     * ### Additional types
     * If you have the `pg_vector` extension installed in your database, you can use the
     * `vector_l2_ops`, `vector_ip_ops`, `vector_cosine_ops`, `vector_l1_ops`, `bit_hamming_ops`, `bit_jaccard_ops`, `halfvec_l2_ops`, `sparsevec_l2_ops` options, which are predefined types.
     *
     * **You can always specify any string you want in the operator class, in case Drizzle doesn't have it natively in its types**
     *
     * @param opClass
     * @returns
