[OT] Postgres Function Cache

On enlightened ones amoung you.

In the face of shabby google results, I hoped that someone hear might know 
something about the postgres function cache.  We have a server which 
reports an error of the form "cache lookup failed for function."  I'd like 
to ideally resolve this without a restart (which I would hope would fix 
this), and have been searching for some way to clear postgres' internal 
function cache - I think it stores plans/hints/compiled-version relating 
to stored proc's.

In any case, I can't seem to find any documentation which tells me how 
this can be cleared and hoped that someone might know of some means to 
achieve this.  Perhaps, I'm searching for the wrong term?

Any help would be of value?
