     * @remarks
     * - By default, Broadcast and Presence are enabled for all projects.
     * - By default, listening to database changes is disabled for new projects due to database performance and security concerns. You can turn it on by managing Realtime's [replication](/docs/guides/api#realtime-api-overview).
     * - You can receive the "previous" data for updates and deletes by setting the table's `REPLICA IDENTITY` to `FULL` (e.g., `ALTER TABLE your_table REPLICA IDENTITY FULL;`).
     * - Row level security is not applied to delete statements. When RLS is enabled and replica identity is set to full, only the primary key is sent to clients.
     *
     * @example Listen to broadcast messages

     * ```
     *
     * @exampleDescription Listen to updates
     * By default, Supabase will send only the updated record. If you want to receive the previous values as well you can

     *
     * ```sql

     *   })
     *   .subscribe()
     * ```
     *
     * @exampleDescription Listen to deletes
     * By default, Supabase does not send deleted records. If you want to receive the deleted record you can
     * enable full replication for the table you are listening to:
     *
     * ```sql
     * alter table "your_table" replica identity full;
     * ```
     *
     * @example Listen to deletes

     *     console.log('Change received!', payload)
     *   })
     *   .subscribe()
     * ```
     *
     * @exampleDescription Listen to multiple events
     * You can chain listeners if you want to listen to multiple events for each table.
     *
     * @example Listen to multiple events
     * ```js
     * supabase
     *   .channel('room1')
     *   .on('postgres_changes', { event: 'INSERT', schema: 'public', table: 'countries' }, handleRecordInserted)
     *   .on('postgres_changes', { event: 'DELETE', schema: 'public', table: 'countries' }, handleRecordDeleted)
     *   .subscribe()
     * ```
     *
     * @exampleDescription Listen to row level changes
     * You can listen to individual rows using the format `{table}:{col}=eq.{val}` - where `{col}` is the column name, and `{val}` is the value which you want to match.
     *
     * @example Listen to row level changes
     * ```js

     * - If you create a channel only to send a REST broadcast, remove it from
     *   the client when the send completes
     *
     * @example Send a message via websocket
     * ```js
     * const channel = supabase.channel('room1')

     * channel.subscribe((status) => {
