While testing 9.1 RPMs on Fedora 15 (2.6.40 kernel), I notice messages like these in the kernel log:
Sep 11 13:38:56 rhl kernel: [ 415.308092] postgres (18040): /proc/18040/oom_adj is deprecated, please use /proc/18040/oom_score_adj instead. These don't show up on every single PG process launch, but that probably just indicates there's a rate-limiter in the kernel reporting mechanism. So it looks like it behooves us to cater for oom_score_adj in the future. The simplest, least risky change that I can think of is to copy-and-paste the relevant #ifdef code block in fork_process.c. If we do that, then it would be up to the packager whether to #define LINUX_OOM_ADJ or LINUX_OOM_SCORE_ADJ or both depending on the behavior he wants. That would be good enough for my own purposes in building Fedora/RHEL packages, since I can predict with confidence which kernel versions a given build is likely to be used with. I think probably the same would be true for most other distro-specific builds. Does anyone want to argue for doing something more complicated, and if so what exactly? regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
