Hi,

When test pg_terminate_backend_and_wait with parallel query.
I noticed that the function is not defined as parallel safe.

I am not very familiar with the standard about whether a function should be parallel safe.
But I found the following function are all defined as parallel safe:

pg_promote
pg_terminate_backend(integer)
pg_sleep*

Is there a reason why pg_terminate_backend_and_wait are not parallel safe ?
(I'm sorry if I miss something in previous mails.)

Best regards,
houzj
