[GENERAL] ERROR: cache lookup failed for type
Hi,
I've been working with SRF and i want to return a setof record but i keep
getting this error ´cache lookup failed for type 18867840´ . My question is
why and how to fix it. I need to do this work as quick as possible so I need
all the help i can get, pleeease .I am including postgres library and i
am using version 8.1.
Where is the code:
#include "SRF_example.h"
#include "postgres.h"
#include "fmgr.h"
#include "funcapi.h"
#include "executor/spi.h"
#include "executor/executor.h"
PG_FUNCTION_INFO_V1(my_SRF_example);
Datum my_SRF_example(PG_FUNCTION_ARGS)
{
FuncCallContext *funcctx;
int call_cntr;
int max_calls;
TupleDesctupdesc;
AttInMetadata *attinmeta;
// stuff done only on the first call of the function
if (SRF_IS_FIRSTCALL())
{
MemoryContext oldcontext;
// create a function context for cross-call persistence
funcctx = SRF_FIRSTCALL_INIT();
// switch to memory context appropriate for multiple function calls
oldcontext = MemoryContextSwitchTo(funcctx->multi_call_memory_ctx);
// total number of tuples to be returned
funcctx->max_calls = PG_GETARG_UINT32(0);
// Build a tuple descriptor for our result type
if (get_call_result_type(fcinfo, NULL, &tupdesc) != TYPEFUNC_COMPOSITE)
ereport(ERROR,
(errcode(ERRCODE_FEATURE_NOT_SUPPORTED),
errmsg("function returning record called in context "
"that cannot accept type record")));
// generate attribute metadata needed later to produce tuples from raw
// C strings
attinmeta = TupleDescGetAttInMetadata(tupdesc);
funcctx->attinmeta = attinmeta;
MemoryContextSwitchTo(oldcontext);
}
// stuff done on every call of the function
funcctx = SRF_PERCALL_SETUP();
call_cntr = funcctx->call_cntr;
max_calls = funcctx->max_calls;
// max_calls -= 1;
attinmeta = funcctx->attinmeta;
elog(NOTICE,"%d < %d",call_cntr,max_calls);
if (call_cntr user_fctx);
SRF_RETURN_DONE(funcctx);
}
}
