The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/9.4/static/explicit-locking.html
Description:
The documentation says :
"This lock mode is not automatically acquired by any PostgreSQL command."
I am wrong if I say that a "ADD CONSTRAINT toto FOREIGN KEY" command will
take a SHARE ROW EXCLUSIVE lock on both tables concerned by the foreign key
?
