Subject: pgsql: Move WAIT_FOR_WAL_* wait events from Client to IPC class
Date: Wed, 08 Jul 2026 18:00:00 +0000
Message-ID: <[email protected]> (raw)

Move WAIT_FOR_WAL_* wait events from Client to IPC class

WAIT_FOR_WAL_FLUSH, WAIT_FOR_WAL_REPLAY, and WAIT_FOR_WAL_WRITE were
placed in the WaitEventClient class.  But WaitEventClient is about
waiting for a socket to become readable or writable, while these events
have other delay sources as well: local fsync and local replay, which
may be disk- or CPU-bound.  WaitEventIPC is a better fit, so move them
there.
