Actually, adding a "pfree(oneres);" to the end of that for loop plugs
the memory leak and allows me to see the error message:
ERROR: Function add_news__test(integer, character varying, timestamp
with time zone, character varying, character varying, character varying,
character varying, integer, timestamp with time zone, integer, timestamp
with time zone, character varying, character varying, character varying,
integer, boolean, character varying, character varying, character
varying, timestamp with time zone, integer, character varying, character
varying, integer) does not exist
Unable to identify a function that satisfies the given argument
types
You may need to add explicit typecasts
Takes a while to check all 16777216 possibilities though, so I'm still
not sure more isn't needed here.
