My pg server log says that this is the problem:

ERROR:  Function acs_message__edit(integer, character varying, character varying, character varying, character varying, text, timestamptz, inte\
ger, character varying, boolean) does not exist
        Unable to identify a function that satisfies the given argument types
        You may need to add explicit typecasts
WARNING:  Error occurred while executing PL/pgSQL function acs_message__new
WARNING:  line 75 at assignment

If there are any pg gurus out there that can provide some insight I'd appreciate it. Notice the reference to the extra varchar argument before the text arg in ...message__edit. Shouldn't there be 3? The rest of the args look ok. TIA
