Junk binary date?

[Kevin Jenkins <gameprogrammer@xxxxxxxxxx>]

I call PQexecParams with the last parameter as 1 to return binary 
data.  I then get this data with:

fileLengthPtr = PQgetvalue(result, rowIndex, fileLengthColumnIndex);
memcpy(&fileLength, fileLengthPtr, sizeof(fileLength));

The value being returned is of type integer.

It should have the value 7237 in binary.
It actually has the value:
fileLengthPtr[0]	0	char
fileLengthPtr[1]	0	char
fileLengthPtr[2]	28 '?'	char
fileLengthPtr[3]	69 'E'	char

Which is not 7237, it's:
fileLength	1159462912	int

Why?
