Обсуждение: new return value of PQfsize

Hi,

the libpq-function PQfsize() now returns
int instead of short. It looks like, that
this needs some adaption in the backend,
because now the size of a variable length
field is returned as 65535 instead of -1.

Oops.  That's libpq's bug, not the backend's.

I thought that the rearrangement of libpq's interface
would be a good time to hide the fact that field sizes are
currently restricted to short --- which was visible in the
return type of PQfsize, and nowhere else in libpq's API.

But I guess I forgot to ensure that sign extension would happen
correctly :-(.  Will fix.
