There is what looks like a bug in 8.3devel. When getting the money type in
binary format from a libpq client, the below error is thrown from the backend:
ERROR: unsupported integer size 8
It appears that the Cash typedef, defined in include/utils/cash.h, has changed
to an int64 (previously an int32). The cash_send and cash_recv functions, in
backend/utils/adt/cash.c, are still calling pq_sendint and pq_getmsgint.
I tested on an 8.2rc box and that did not suffer from this issue because it uses
a 32-bit Cash type.
Below is a test to reproduce the issue.
create table money_test (amount money);
insert into money_test values ('13.85');
/* libpq test code (breaks on 8.3devel, works on 8.2rc) */
#include <libpq-fe.h>
#include <stdio.h>
int main(void)
{
PGresult *res;
PGconn *conn = PQconnectdb("hostaddr=127.0.0.1 user=postgres");
if(PQstatus(conn) != CONNECTION_OK)
{
printf("connection failure\n");
return 1;
}
res = PQexecParams(
conn,
"SELECT amount FROM money_test LIMIT 1",
0,
(const Oid *)NULL,
(const char * const *)NULL,
(const int *)NULL,
(const int *)NULL,
1); /* binary */
printf("tuples=%d, err=%s, res_err=%s\n",
PQntuples(res),
PQerrorMessage(conn),
PQresultErrorMessage(res));
PQclear(res);
PQfinish(conn);
return 0;
}
