# When using the methods "add_concurrent_index" or "remove_concurrent_index"
# you must disable the use of transactions

# as these methods can not run in an existing transaction.
# When using "add_concurrent_index" or "remove_concurrent_index" methods make sure
# that either of them 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 or removing fails
# and can be retried or reverted easily.
#
# To disable transactions uncomment the following line and remove these
# comments:
# disable_ddl_transaction!
