When I look in RDB$TRIGGERS this is the only thing:

RDB$USER_PRIVILEGES
RDB$TRIGGERS
RDB$TRIGGERS
RDB$RELATIONS
RDB$RELATIONS
RDB$GENERATORS
RDB$RELATION_CONSTRAINTS
RDB$RELATION_CONSTRAINTS
RDB$RELATION_CONSTRAINTS
RDB$RELATION_CONSTRAINTS
RDB$REF_CONSTRAINTS
RDB$REF_CONSTRAINTS
RDB$CHECK_CONSTRAINTS
RDB$CHECK_CONSTRAINTS
RDB$CHECK_CONSTRAINTS
RDB$INDEX_SEGMENTS
RDB$INDEX_SEGMENTS
RDB$INDICES
RDB$INDICES
RDB$TRIGGERS
RDB$TRIGGERS
RDB$RELATION_FIELDS
RDB$RELATION_FIELDS
RDB$RELATION_FIELDS
RDB$PROCEDURES
RDB$PROCEDURES
RDB$EXCEPTIONS
RDB$USER_PRIVILEGES
RDB$USER_PRIVILEGES
RDB$USER_PRIVILEGES
RDB$RELATION_CONSTRAINTS
RDB$CHECK_CONSTRAINTS
RDB$FIELDS

But I guess those are there for a reason ?
