On a linux box (Linux db1 2.6.18.8-md #1 SMP Wed May 23 17:21:37 EDT
2007 i686 GNU/Linux)
I edited postgresql.conf and changed:
shared_buffers = 5000 work_mem = 16384
max_stack_depth = 4096
and then restarted postgres. The puzzling part is that postgres
actually started. When I have done this on other boxes, I had to edit
kernel settings to allow for more shared memory.
The kernel settings are currently:
shmmax: 33554432
shmall: 2097152
I would have expected to need to increase these before postgres would run.
I have a nagging suspicion that something isn't right. Like it's not
actually reading the conf file, or I might have a problem on reboot.
I'm not sure if I'm worrying about nothing, or if something weird is
going on.

TIP 5: don't forget to increase your free space map settings
