People have tried to raise awareness of it; sample:
http://lkml.org/lkml/2007/2/9/275
without much success. The Linux kernel hackers dislike the whole approach
PostgreSQL uses to allocate shared memory anyway--witness the backlash
against any attempt to raise SHMMAX.
I found the long thread that beats this issue to death in the archives
again:
http://archives.postgresql.org/pgsql-hackers/2008-02/msg00026.php
That discussion should get raised to a higher profile eventually, maybe a
summary on the wiki.
