This looks strange to me, but it works:

pgslekt=> CREATE TABLE participant_notes (
pgslekt(>     person_fk   INTEGER NOT NULL,
pgslekt(>     event_fk    INTEGER NOT NULL,
pgslekt(>     part_note   TEXT,
pgslekt(>     PRIMARY KEY (person_fk, event_fk),
pgslekt(>     FOREIGN KEY (person_fk, event_fk) REFERENCES participants 
(person_fk, event_fk)
pgslekt(> );
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index 
"participant_notes_pkey" for table "participant_notes"
CREATE TABLE

And is probably what I want.
