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
