FWIW, pg_classy[1], which is still a work in progress, would allow for 
that. The idea is that you define a code template which you can then 
call with arguments (such as the name of a matview table), and those 
arguments get put into the template before executing the resulting SQL.

Most of the basic framework for that is in place; I just need to finish 
code that will allow for the extension to track arbitrary database 
objects that were created.
