Hi,

Yes, paramLengthts is a NULL pointer. But, is SegFault an expected result?

Himms... When I take a look at src/interfaces/libpq/fe-exec.c:

956 if (paramValues && paramValues[i])
957 {
958     int         nbytes;
960     if (paramFormats && paramFormats[i] !=3D 0)
961     {
962         /* binary parameter */
963         nbytes =3D paramLengths[i];

It appears to be SegFault was caused by paramLengths[i] on line 963.
So, this means, user _has_to_ specify the size of input while using
binary data. Maybe a "if ( paramLengths )" check can be useful.

Regards.
