How it works…

Restoring a single table from a logical backup is relatively easy, as each logical object is backed up separately from the others, and its data and metadata can be filtered out.

However, a physical backup is composed by a set of binary data files, in a complex storage format that can be interpreted by a PostgreSQL engine.

This means that the only way to extract individual objects from it, at present, is to restore the backup on a new instance, and then make a logical dump as explained in the previous recipe: there's no way to restore a single table from a physical backup in just a single step.
