hostaddr with Postgres 9.4

I observe this error on Fedora Rawhide:

  1) PG::Connection can retrieve it's connection parameters for the established connection
     Failure/Error: expect( @conn.hostaddr ).to eq( nil ) if @conn.server_version >= 9_04_00
     NoMethodError:
       undefined method `hostaddr' for #<PG::Connection:0x000000030dc8e0>
     # ./spec/pg/connection_spec.rb:166:in `block (2 levels) in <top (required)>'
     # ./spec/helpers.rb:29:in `block in included'

although I have postgres 9.4 installed:

$ rpm -q postgresql-devel
postgresql-devel-9.4.0-1.fc22.x86_64

This is apparently due to:

checking for PQhostaddr()... no

And it seems tath PQhostadd was reverted from 9.4:

Revert "Add PG::Connection#hostaddr. This is new in PostgreSQL-9.4."

PQhostaddr was removed from final PostgreSQL-9.4.0.

This fixes issue #202 :#202

This reverts commit 03deab7.

Thanks for reporting this issue. Our travic-ci was still running on PostgreSQL-9.4-beta3, but it is updated now: https://travis-ci.org/larskanis/ruby-pg/builds
