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.
