Hi,
  I'm having problems loading (insert into ..) a c array into a postgres
table.
I have tried all the variations on syntax I can think of, and searched for
the
answer... and either didn't find it or didn't recognize it..

SHORT version:
How do I replace {1,2...} with a c array,
exec sql insert into testtab (fname,fid,farr) values
(:fname,:fid,'{1,2,3,4,5,6,7,8,9}');
?

LONG,LONG version:
typos are mine (I have to retype from the system I'm running postgres :( )
I can do this in psql:
create type int2array
(input=array_in,output=array_out,internallength=variable,element=int2);
create table sampletab2 (id int4, narr int2array);
insert into sampletab2 (id,narr) values (12,'{3,2}');
and everything looks ok with both \d sampletab2 and select * from sampletab2

And this code works great:
#include <stdio.h>
#include <libpq-fe.h>
#include <math.h>

exec sql whenever sqlerror sqlprint;
exec sql include sqlca;

exec sql begin declare section;
  int fid;
  int fidarr[10];
  varchar[40];
  varchar sqlcom[80];
exec sql end declare section;

main(){
  int ii;
  printf("Begin \n");
  fid=5;
  for (ii=0;ii<=9;ii++) {fidarr[ii]=ii;printf("fidarr[%d]=%d
\n",ii,fidarr[ii]);};
  fname.len=sprintf(fname.arr,"doodah day");
  printf("fid equals : %d \n",fid);
  exec sql connect to testdb1;
  exec sql create table testtab (fname varchar(40),fid int, fidarr int[10]);
  exec sql insert into testtab (fname,fid,farr) values
(:fname,:fid,'{1,2,3,4,5,6,7,8,9}');
  exec sql commit;
  exec sql disconnect;
  printf ("Done \n");
}

How do a do something like:
exec sql insert into testtab (fname,fid,farr) values (:fname,:fid,:fidarr);

??
Thanks (and sorry for the long post)
andrew.
