Postgresql 9.3 Released
Foreign key deadlock fix finally after 5 years is out to production! Hopefuly now it is safe to use foreign keys in postgresql :)Haveing table A, B, C with FK in A and B to C_column1, running function which updates A and other function which updates B, both refering to same C row via FK, but not modyfing it in any way - causes deadlock.in pre 9.3, now its fixed, so I can use FKs again after so many years and its just creazy:)
