Hi,
I%u2019ve detected problem with using psqlodbc driver on Sun Sparc Solaris platform.
An error occurs when Sparc converts unsigned short to unsigned int and back to unsigned short.
With default implementation 00 00 01 02 is converted to 00 00 (last two bytes are skipped), but it should be converted
to01 and 02.
Problem occurs every time when through method SOCK_put_int two bytes integer was transferred and doesn%u2019t allow
usingPGAPI_PutData (odbc_lo_write) to put large objects to database.
To resolve described problem I%u2019ve attached patch bellow.
Regards
Marcin

if (!self)
return;
switch (len)

case 2:

+ unsigned short rv;
rv = self->reverse ? value : htons((unsigned short) value);
SOCK_put_n_char(self, (char *) &rv, 2);
return;

case 4:
+ {
+ unsigned int rv;
rv = self->reverse ? value : htonl((unsigned int) value);
SOCK_put_n_char(self, (char *) &rv, 4);
return;

default:
SOCK_set_error(self, SOCKET_PUT_INT_WRONG_LENGTH, "Cannot write ints of that length");
