 * the bootstrap parser will turn into DefineIndex commands.
 *
 * The keyword is DECLARE_INDEX or DECLARE_UNIQUE_INDEX.  The first two
 * arguments are the index name and OID, the rest is much like a standard
 * 'create index' SQL command.
 *
 * For each index, we also provide a #define for its OID.  References to
 * the index in the C code should always use these #defines, not the actual
 * index name (much less the numeric OID).
