RE: [PROPOSAL] Termination of Background Workers for ALTER/DROP DATABASE - Mailing list pgsql-hackers

Dear Iwata-san,

Thanks for updating the patch.

> And I also removed AcceptBackgroundWorkerCancel() function.
> Please check my attached patch.

```
+/*
+ * Cancel background workers.
+ */
+void
+CancelBackgroundWorkers(Oid databaseId, int cancel_flags)
```

Do we still need the cancel_flags? I cannot find other reasons to terminate
workers. Also the things I don't like is that BGWORKER_CANCEL_ADMIN_COMMANDS must
have the same value as BGWORKER_EXIT_AT_DATABASE_DROP. Only one flag exists but
it has 0x0004. Can we remove the argument and flags from the patch?
