More investigation needed

This happens e.g. with the following schema:

CREATE TABLE t_5972_referenced (
  a INT, 
  b INT, 
  CONSTRAINT pk_t5972_referenced PRIMARY KEY (a), 
  CONSTRAINT uk_t5972_referenced UNIQUE (a, b)
);

CREATE TABLE t_5972_referencing (
  a INT, 
  b INT, 
  CONSTRAINT fk_t5972_referenced FOREIGN KEY (a, b) REFERENCES t_5972_referenced (a, b)
);

This seems to have been fixed in H2 in the meantime.
