Re: Libpq support to connect to standby server as priority

Question about 0001.  In the CONNECTION_SETENV state, you end by falling
through to the CONNECTION_CHECK_TARGET case; but in that switch it seems
a bit unnatural to do that.  I think doing "goto keep_trying" is another
way of doing the same thing, but more in line with what every other
piece of code does.
