Hi Adrian,

I am running the function "select test_notice();" from the psql console with psql/server versions 15beta1.

In psql 15beta1, the notice appears only after the function returns/transaction completes.

If I execute the same function from psql 14.3 and server 15beta1, the notice appears on the psql console immediately as expected, before the pg_sleep() completes.

It's reproducible for me, I just double checked it.

I think Tom was able to reproduce this by the sounds of his response?

Best regards,

Alastair
