Im getting this error when trying to make a migration on my Ruby App.
I have already made it: sudo apt-get install postgresql-9.3
but the error persists.
ActiveRecord::StatementInvalid: PG::UndefinedFile: ERROR: could not open extension control file “/usr/share/postgresql/9.3/extension/hstore.control”: No such file or directory
: CREATE EXTENSION IF NOT EXISTS “hstore”
