Hmm... seems like an issue with the activerecord PostgreSQL adapter:

https://rails.lighthouseapp.com/projects/8994/tickets/6187-postgresql-and-rails-303-migrations-fail-with-index-name-length-64-chars

and I see that Hobo simply inquires about the max length from the model's 
connection (in index_spec.rb):

        if check_name.length > @model.connection.index_name_length
          r += ", :name => '#{name[0,@model.connection.index_name_length]}'"
          $stderr.puts("WARNING: index name #{check_name} too long, 
trimming")

So, if this is the case, is there any way for me to intervene in the name 
that HObo's migration generator comes up with?

Or, should Hobo be using index_name_length-1 ?
