* definition of the system "opclass" relation (pg_opclass)
* along with the relation's initial contents.
*
+ * New definition for Postgres 7.2: the primary key for this table is
+ * <opcamid, opcname> --- that is, there is a row for each valid combination
+ * of opclass name and index access method type. This row specifies the
+ * expected input data type for the opclass (the type of the heap column,
+ * or the function output type in the case of a functional index). Note
+ * that types binary-compatible with the specified type will be accepted too.
+ *
+ * For a given <opcamid, opcintype> pair, there can be at most one row that
+ * has opcdefault = true; this row is the default opclass for such data in
+ * such an index.
+ *
+ * Normally opckeytype = InvalidOid (zero), indicating that the data stored
+ * in the index is the same as the input data. If opckeytype is nonzero
+ * then it indicates that a conversion step is needed to produce the stored
+ * index data, which will be of type opckeytype (which might be the same or
+ * different from the input data). Performing such a conversion is the
+ * responsibility of the index access method --- not all AMs support this.
+ *
