Subject: pgsql: Add maintenance_io_concurrency flag to some read stream users
Date: Mon, 28 Apr 2025 18:20:46 +0000
Message-ID: <E1u9T5y-0002qW-2L@gemulon.postgresql.org> (raw)
Add maintenance_io_concurrency flag to some read stream users
Index vacuuming and [auto]prewarm AIO concurrency should be governed by
maintenance_io_concurrency. As such, pass those read stream users the
READ_STREAM_MAINTENANCE flag which will calculate their read stream
distance with maintenance_io_concurrency instead of
effective_io_concurrency. This was an oversight in the original commits
making those operations use the read stream API.
