Thanks very much for your prompt help on this lads.

So in the following code

StringInfo	buf = (StringInfo) PG_GETARG_POINTER(0)
// ...
Oid element_type = pq_getmsgint(buf, sizeof(Oid));

are the bytes representing an int4 Oid simply 23, represented in variable buf as

[0x17][0x00][0x00][0x00]

The reason for asking is I'm under the impression there can be
differences between network byte-order and other representations.
Hopefully this isn't an inane question - apologies if it is.

Regards,

Michael
