This is an SQL runner that will launch the given command only if
the used DBMS is PostgreSQL.
"""SQL runner for PostgreSQL-only queries.
It may be useful to run Postgres' specific SQL, or to take actions
that would be non-senses with backends other than Postgre, such
as disabling particular constraints that would prevent the migration
to run successfully.
If used on another DBMS than Postgres, it will be a noop.
See `club/migrations/0010_auto_20170912_2028.py` as an example.
