-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Is there any documentation other than the soruce code on how postgres performs the appropriate (PK, FK, CHECK, UNIQUE) constraint enforcement on DELETEs, UPDATEs, and INSERTs? What I'm trying to figure out is how postgre identifies the *exact* set of constraints to enforce for each of the different commands above, and the order in which these are performed (since some checks are way more expensive than others). Thank you, Demian -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFF1IcYWs7G5iIp9akRAgM4AKChLgEMZRJC36hpEPDtPBPjrVfFJwCfSe43 B1KNLqOsn5qQnbXPnup2n7A= =kABQ -----END PGP SIGNATURE-----
