Luke Faraone f0afa56cd3 [manual] South migration for Subscriptions model change.
Autogenerated schema migration:
 + Added field in_home_view on zephyr.Subscription

To do this manual change, you need to run:
    python manage.py migrate zephyr 0005

on staging. No action is required on prod since there is a shared database.

Zev Benjamin c6d196a22f [manual] Add South migration for creating a Postgres full text index of messages
This schema migration is only for use in automated migrations.  To
deploy on the production database (the migration only needs to be
done once for both of staging and prod because they share a
database), you should instead execute the following SQL manually:

$ ssh postgres.humbughq.com
$ psql
humbug=> CREATE INDEX CONCURRENTLY zephyr_message_full_text_idx ON zephyr_message USING gin(to_tsvector('english', subject || ' ' || content));

Note the addition of the "CONCURRENTLY" keyword.  The problem is that
creating the index takes non-trivial time and requires a write lock
on the table while the index is being created.  This would mean that
users would be unable to send messages while we were generating the
index, which isn't acceptable.  We can't create the index
concurrently in the South migration because concurrent index
creations can't happen inside of a transaction and South forces a
transaction on migration functions.

Also note that this index must be created before Postgres full text
search is deployed to the app because full text search without an index
is actually much slower than plain search using the LIKE operator.
