 *
 * pg_opclass.h
 *	  definition of the system "opclass" relation (pg_opclass)
 *	  along with the relation's initial contents.
 *
 * The primary key for this table is <opcmethod, opcname, opcnamespace> ---
 * 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 expression output type
 * in the case of an index expression).  Note that types binary-coercible to
 * the specified type will be accepted too.
 *
 * For a given <opcmethod, 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.  (This is not currently enforced by an index, because we
 * don't support partial indexes on system catalogs.)
 *
 * Normally opckeytype = InvalidOid (zero), indicating that the data stored
 * in the index is the same as the data in the indexed column.  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 datatype).  Performing such a
 * conversion is the responsibility of the index access method --- not all
 * AMs support this.
