Subject: pgsql: Handle interrupts while waiting on Append's async subplans
Date: Wed, 12 Mar 2025 19:15:21 +0000
Message-ID: <[email protected]> (raw)
Handle interrupts while waiting on Append's async subplans
We did not wake up on interrupts while waiting on async events on an
async-capable append node. For example, if you tried to cancel the
query, nothing would happen until one of the async subplans becomes
readable. To fix, add WL_LATCH_SET to the WaitEventSet.
Backpatch down to v14 where async Append execution was introduced.
