Agreed with you and Sawada-San about having a test. BTW, shall we
slightly tweak the documentation [1]: "The subscription apply process
will, at a session level, run with the privileges of the subscription
owner. However, when performing an insert, update, delete, or truncate
operation on a particular table, it will switch roles to the table
owner and perform the operation with the table owner's privileges." to
be bit more specific about initial sync process as well?
