Hi
I just installed an openSUSE 12.3 64Bit on an i5 box with 32GB RAM.
Then I installed postgresql 9.2.4 from their repository.
The pg service starts with default config.
As default it has only 24 MB shared_buffers.
I need it way higher like 4 or even 8 GB.
As soon I change those 24 MB to something higher, PG won't start anymore.
I had the same issue back with openSUSE 12.1 and it was solved when I
switched from systemd back to sysvinit.
How can I get more memory for PG on openSUSE 12.3 ?
Regards
Andreas

OK I think that did it :)
I'm just wondering what point it could be to set the default limits so
low in the first place as plenty of memory is so common these days.

The type of shared memory postgresql uses is rarely used by other
systems. However, as I recall 9.3 resolves the shmmax issue as a whole
so it won't be a problem.

Yes, by reducing system v shared memory consumption:
