# When using the methods "add_concurrent_index" or "add_column_with_default"
|
|
# you must disable the use of transactions as these methods can not run in an
|
|
# existing transaction. When using "add_concurrent_index" make sure that this
|
|
# method is the _only_ method called in the migration, any other changes
|
|
# should go in a separate migration. This ensures that upon failure _only_ the
|
|
# index creation fails and can be retried or reverted easily.

# To disable transactions uncomment the following line and remove these
|
|
# comments:

# disable_ddl_transaction!
