Creating a SQL variable to hold a table name

Yow, there's got to be an easier way to do this ...

I'm trying to create a script file that will process a table whose name
is constructed from an integer argument passed into the script file. E.g.,

$ psql -f my_script.sql -v id=24
....
DELETE FROM table_00024 WHERE ...

Here's what I came up with so far:
\set QUIET 1
\pset footer 0
\o /tmp/reset_this_id.sql
\qecho '\\set this_table `printf \'table_%.5d\'' :id '`'
\o
\i /tmp/reset_this_id.sql

\qecho :id
\qecho :this_table

So, it works, but I'm wondering if I missed an easy alternative.
