If that's what you need you can always change the system catalogs
manually. For CHAR(n) and VARCHAR(n) you change pg_attribute.atttypmod
to (n+4). For NUMERIC(n,m) it's something like (n<<16) + m + 4 or maybe
(m<<16) + n + 4, don't remember right now.
Be sure to check that your data is in a safe place before you do this,
and double check before you commit the transaction if you do it
manually.
