This is what i set my tupdesc to. => tupdesc = trigdata->tg_relation->rd_att;
i am using the code like this. the do_log function to log the flow. it gives all correct until it reaches
the line :-
disposition=SPI_getvalue(trigdata->tg_trigtuple, tupdesc, 13); do_log("Got disposition"); ======>
itstops logging from here.
do_log("Entered the main trigger logic"); =========> success if
(TRIGGER_FIRED_BEFORE(trigdata->tg_event))when = "before"; else when = "after ";
tupdesc = trigdata->tg_relation->rd_att; if ((ret = SPI_connect()) < 0)
do_log("SPI_connect failed"); else { sprintf(logs,"SPI_connect success, fired
%s",when); ======> success do_log(logs); } ret = SPI_exec("SELECT
count(*)FROM ast_cdr", 0);
if (ret < 0){ sprintf(logs, "trigf (fired %s): SPI_exec returned %d", when, ret);
do_log(logs); }
/* count(*) returns int8, so be careful to convert */ i =
DatumGetInt64(SPI_getbinval(SPI_tuptable->vals[0],tupdesc, 1, &isnull)); sprintf(logs, "trigf (fired %s):
thereare %d rows in ast_cdr", when, i); ====> success do_log(logs);
disposition=SPI_getvalue(trigdata->tg_trigtuple, tupdesc, 13); =====> failed.
do_log("Got disposition"); ===============> doesnot reach here.
With warm regards.

================== it fails here because i tried to get logs before this
statement and it succeeded.
