This is an InnoDB extension to standard SQL." This is possibly also worth noting. I'm not sure how PostgeSQL handles foreign key constraints on non-unique keys, but I know we have at least two of these in kohastructure.sql at the moment. -- You are receiving this mail because: You are watching all bug changes.
