the syntax in migration wrong. remove_index method takes 1 standard parameter , named parameters. migration in question has 2 standard parameters , 1 named parameter.

http://apidock.com/rails/activerecord/connectionadapters/schemastatements/remove_index

remove_index("instances", ["catalog_id"], {:name=>"index_instances_on_catalog_id"}) 

should be

remove_index("instances", column: 'catalog_id', name: 'index_instances_on_catalog_id') 

this untested code, verify ahead of time. can grab copy of production database , run rake db:migrate locally test , debug.
