channel.onPostgresChange giving compile errors

[sahildhull2512]

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

channel.onPostgresChange() and channel.on() are giving compile errors

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

Run this code snippet

let channel = supabase.realtimeV2.channel("public:chat_messages")

channel.onPostgresChange(
  event: .insert,
  schema: "public",
  table: "chat_messages"
) { payload in
  print("received payload", payload)
}

Error:

No exact matches in call to instance method 'onPostgresChange'

Expected behavior

I expected it to compile. Same issue with channel.on() function

Hi, @sahildhull2512

That is not the correct way to use the method, you should use

let channel = supabase.realtimeV2.channel("public:chat_messages")
var tokens = Set<ObservationToken>()

channel.onPostgresChange(
  InsertAction.self,
  schema: "public",
  table: "chat_messages"
) { payload in
  print("received payload", payload)
}
.store(in: &tokens)

The event isn't an enum you access as .insert, but a type that you pass as InsertAction.self.

Where did you see the usage as event: .insert? Is it under one of our docs? If so I need to fix it.
