No.
Copying the 10 billion rows in only consumes one xid.
- If you're in "autocommit mode," then each SQL statement consumes one
xid.
- If you type in BEGIN;, then you could have 10 billion SQL
statements after that, and they would, altogether, consume 1 xid.

To iterate is human; to recurse, divine.
