Currently, it's not available. But a similar feature is already requested here - https://redmine.postgresql.org/issues/1761. It will allow select/deselect objects when taking backup of a database.
I have a database with a few hundred tables. I'd like to print the schema for two tables to take with me while I'm traveling so that I can work out a problem. I see no way of printing out the schema for a couple of tables (presumably one at a time). Is there?
