[debian-mysql] Bug#1034770: mariadb-server-10.5: Fix for MDEV-29988 (part of 10.5.19) needs to be in stable

[Xan Charbonnet]

Package: mariadb-server-10.5
Version: 1:10.5.18-0+deb11u1
Severity: important

Dear maintainer,

The update in bullseye from 10.5.15 to 10.5.18 on December 4, 2022 contained a
major performance problem for some workloads.  It causes my DNS server running
PowerDNS with a MariaDB backend to run out of memory.

This was reported in Debian Bug 1027337:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1027337
and fixed by putting 10.5.19 into unstable.

However, I (and presumably others?) run stable for my DNS servers, and I'm
still stuck on 10.5.15.

If anything could be done I would appreciate it.  Thanks.
