used by the index for that column.\n * For example, a B-tree index on four-byte integers would use the int4_ops class;\n * this operator class includes comparison functions for four-byte integers.\n * In practice the default operator class for the column's data type is usually sufficient.\n * The main point of having operator classes is that for some data types, there could be more than one meaningful ordering.\n * For example, we might want to sort a complex-number data type either by absolute value or by real part.\n * We could do this by defining two operator classes for the data type and then selecting the proper class when creating an index.\n * More information about operator classes check:\n *\n * ### Useful links\n * https://www.postgresql.org/docs/current/sql-createindex.html\n *\n * https://www.postgresql.org/docs/current/indexes-opclass.html\n *\n * https://www.postgresql.org/docs/current/xindex.html\n *\n * ### Additional types\n * If you have the `pg_vector` extension installed in your database, you can use the\n * `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.\n *\n * **You can always specify any string you want in the operator class, in case

used by the index for that column.\n * For example, a B-tree index on four-byte integers would use the int4_ops class;\n * this operator class includes comparison functions for four-byte integers.\n * In practice the default operator class for the column's data type is usually sufficient.\n * The main point of having operator classes is that for some data types, there could be more than one meaningful ordering.\n * For example, we might want to sort a complex-number data type either by absolute value or by real part.\n * We could do this by defining two operator classes for the data type and then selecting the proper class when creating an index.\n * More information about operator classes check:\n *\n * ### Useful links\n * https://www.postgresql.org/docs/current/sql-createindex.html\n *\n * https://www.postgresql.org/docs/current/indexes-opclass.html\n *\n * https://www.postgresql.org/docs/current/xindex.html\n *\n * ### Additional types\n * If you have the `pg_vector` extension installed in your database, you can use the\n * `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.\n *\n * **You can always specify any string you want in the operator class, in case
