Yep, and just like that question, sometimes any valid answer is fine. 
You might not care if it's $1 + .5 + .2 + .02 + .01 or 183 * 0.01, so 
long as the result is the same.

This is turning out to be a reasonably common question, where people 
want to be able to use functionality of pg_dump from _within_ the 
database system.

If the INFORMATION_SCHEMA isn't sufficient for the OP's purposes or is 
too clumsy for re-creating DDL from, there's another option. It's ugly, 
but you can add a plpythonu or plperlu server-side function that calls 
the server's copy of pg_dump and spits the resulting text back to the 
client.
