Yes, we support NaN's and Inf.
Hmph. Apparently their strtod() has thought of some original new way to misbehave on those inputs. Would you mind tracing through float4in() or float8in() to see exactly how it manages to fail?
regards, tom lane
I ran a quick C test:
cc -O -o test3 test3.c
$ ./test3
num=nan
errno=0
$ cat test3.c
#include <stdlib.h>
#include <stdio.h>
#include <errno.h>
int main(int argc,char **argv)
{
double num;
char *input="NaN";
char **ptr; num=strtod(input,ptr);
printf("num=%g\n",num);
printf("errno=%ld\n",errno);
exit(0);
}So, how's the easiest way to trace PG's float4in stuff?
