First what has this to do with the subject, in particular "'DEFERRABLE
INITIALLY DEFERRED"?
The error seems fairly straight forward:
ERROR: insert or update on table "site" violates foreign key constraint
"site_owner_fkey"
DETAIL: Key (owner)=(3a83db7f-c82e-4b7a-a5c7-c0b43f415b0e) is not
present in table "site_owner"
To understand more we will need to see the schema for:
site_owner
site
including the FK relationship between them.
Also what is creating the owner key in site_owner as I do not see that
field in the INSERT to site_owner.
