Thank you very much! pgslekt=> CREATE TABLE participant_notes ( pgslekt(> person_fk INTEGER, pgslekt(> event_fk INTEGER, pgslekt(> part_note TEXT, pgslekt(> FOREIGN KEY (person_fk, event_fk) REFERENCES participants (person_fk, event_fk) pgslekt(> ); CREATE TABLE I'd missed that particular syntax. This table is now without a primary key, but is that a problem? I don't expect it to grow beyond maybe a few thousand rows. -- Leif Biberg Kristensen http://solumslekt.org -- Sent via pgsql-sql mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
