/** read_back_view_ddl()
Load back VIEW code from the database for everything we created, so that we know how it was normalized.
This will go through the whole catalog and read the SQL definition for each view. This is needed because
the server stores the view definition in a canonical form, which is quite different from what the user
types (not only formatting is stripped, but object names are expanded and expressions are rewritten).
That makes it impossible for us to synchronize by comparing the definition in the model with the
definition in the server. So we need to store the server version of the view right after we create it in
there and a snapshot of the view that was used to create that view.
During synchronization, we can detect changes in the model by comparing the model version of the snapshot with
the model SQL definition and detect server changes by comparing the server version of the definition with
the snapshot for the server. We need to do that separately for every target server that synchronization is
used with (using the db.SyncProfile object).
