Hi All,

Is there a function in the catalogs somewhere that will split this?:

australia=# select tgargs from pg_trigger where oid=3842228;
tgargs

----------------------------------------------------------------------------
------
--------------

<unnamed>\000users_mealplans_prefs\000medidiets_meals\000UNSPECIFIED\000meal
_id\0
00meal_id\000
(1 row)

I'm hoping to do the splitting within pl/pgsql even. If there is no
function to break it up, can someone please suggest how I would code taking
this string and breaking it into components.

Chris
