Operating system:   windows 64 bit
Description:

Function PQsocket from libpq returns int. But on win64, int type has 32
bits, and socket handle has 64 bits. 
PQsocket must return а different type, may be ptrdiff_t.

We can't just redefine the result type of PQsocket without
causing API/ABI breakage everywhere.

Perhaps it would be worth inventing a Windows-only function that
returns a connection's socket handle.  There hasn't been much
demand for that though.
