Re: droped out precise time calculations in src/interfaces/libpq/fe-connect.c

I will keep this in case we need it later.  I think we worked around
this problem by having timeout == 1 set equal to 2 so we get at least
one second for the connection.

belivethat fine time calculation is the right way.
