Re: Starting with pl/pgsql..

I poked a bit further and looked broken dependancies for views, PL/pgSQL
functions and triggers. It looks like PostgreSQL already handles the
trigger dependancy correctly. The function relation/OID resolution is
cached for the lifetime of the backend process. Once I quit and
reconnected it reresolved the table name again. The issue remained for the
view object.

So... A function could be created to drop the view and recreate it from
the saved source function.
