 * Revision 1.2  2000/11/19 07:02:49  fsg
 * Change in show.e to use CHARACTER_LENGTH instead of FIELD_LENGTH in
 * SHOW PROCEDURE
 *
 * 19-May-2001 Claudio Valderrama.
 * Change to be in sync with extract.e: BLOB is not returned
 * by value but by descriptor.
 * 2001.09.21 Claudio Valderrama: Show correct mechanism for UDF parameters.
 * 2001.10.01 Claudio Valderrama: SHOW GRANTS works without any argument, too.
 *   Metadata extraction is slightly faster if SHOW_grants() knows the obj_type.
 *   Keyword USER is written when the grantee is a user and since the engine
 *   now supports GRANT...to ROLE role_name, ROLE is written when the grantee is
 *   indeed a role. When the grantee is a group, it's shown, too.
 * 2003.02.04 Dmitry Yemanov: support for universal triggers
