Ahhh yes I got it now :) I was pulling in the wrong field from the inner
nested record set which was causing it to call itself as you suggested.
I did suspect this and put a RAISE NOTICE at the beginning of the
function to try and debug it, but the message was only displayed perhaps
once every several hundred lines of output between many "CONTEXT:
PL/pgSQL function "findsubcategories" line 15 at for over" messages,
which made me think that something was being overwritten in the
recursion (for an infinite recursion I would have expected the screen to
fill with hundreds of RAISE NOTICE message until something died).
Anyway, it all seems to be working now - thanks very much for the help.
Mark.
