There could be a number of queries used for monitoring or
administration which will be affected.  Just on our Wiki pages we
have some queries available for copy/paste which would need multiple
versions while both column names were in supported versions of the
software:
http://wiki.postgresql.org/wiki/Lock_dependency_information
http://wiki.postgresql.org/wiki/Lock_Monitoring
http://wiki.postgresql.org/wiki/Backend_killer_function
I agree that these are manageable, but not necessarily trivial. 
(You should see how long it can take to get them to install new
monitoring software to our centralized system here.)  I think that's
consistent with the "save up our breaking changes to do them all at
once" approach.
