When accessed over IPv6, the ip address of the user is a 128-bit number, too big for PostgreSQL's bigint data type. Since PostgresSQL has the built-in inet type, which handles both IPv4 and IPv6 addresses, we should use that instead. Where this is done elsewhere in the codebase, the column is called ip_address, so we should follow that convention as well. This migration uses a SQL command to populate the new field from the old one, so as not to rely on the TopicLinkClick model class, which should keep the migration from failing if that class is modified in the future.
