Actually, I think not removing devel/headers/doc package seems to be the
only thing you did wrong. Yes you can't remove libevent, but you can
remove libevent-devel package.

Now, there can be two libevent versions (1.4 and 2) present on system,
but postgresql repo doesn't provide development package for libevent
1.4. So new packages will have to be built with libevent 2. If you
strictly need to build package against old libevent (I hope not), than
this way won't work for you unless you make your own rebuild of libevent
which solves this problem..
