I have a bunch of views, and some views use data from other views.
... Several times now, as I got further into the project, I've changed how I make some views and I've had to redefine not just that view, but all the ones that depend on it.
2. Create a list of all data base objects from the dump file
pg_restore -l mydatabase.dump > mydatabase.list
3. Edit the list file and delete all rows except those for your views A, B, and C. Make sure you leave the lines corresponding to those views in the order in which they appear in the list file, as the following step will then have commands in the right dependency order.
4. Generate a SQL command file, based on the dump and the edited list file:
