# This patches ActiveRecord so indexes created using the MySQL adapter ignore
# any PostgreSQL specific options (e.g. `using: :gin`).
#
# These patches do the following for MySQL:
#
# 1. Indexes created using the :opclasses option are ignored (as they serve no
# purpose on MySQL).
# 2. When creating an index with `using: :gin` the `using` option is discarded
# as :gin is not a valid value for MySQL.
# 3. The `:opclasses` option is stripped from add_index_options in case it's
# used anywhere other than in the add_index methods.
