pg_opclass.h

PostgreSQL 8.1.4的源码 适用于Linux下的开源数据库系统

/*-------------------------------------------------------------------------
 *
 * pg_opclass.h
 *	  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 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 <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 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.
