Re: select count() out of memory - Mailing list pgsql-general

Hi

I have tried to answer to the best of my knowledge but its running on
Soalris 10, and I am not that familiar with solaris ( Go Linux!!! :)

the machine has 32GB RAM, I dont know how much swap it has, but I do know
the disk system is a disk cluster with 16x450GB disks, it probably has a
local disk as well but I dont know how big it is.

-bash-3.00$ ulimit -a
core file size        (blocks, -c) unlimited
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
open files                    (-n) 256
pipe size          (512 bytes, -p) 10
stack size            (kbytes, -s) 10240
cpu time             (seconds, -t) unlimited
max user processes            (-u) 16357
virtual memory        (kbytes, -v) unlimited


this is my config

checkpoint_segments = 96
effective_cache_size = 128000
shared_buffers = 430000
max_fsm_pages = 208000
max_fsm_relations = 10000

max_connections = 1000

autovacuum = off                        # enable autovacuum subprocess?

fsync = on                              # turns forced synchronization on
or off
#full_page_writes = on                  # recover from partial page writes
wal_sync_method = fdatasync
wal_buffers = 256

commit_delay = 5
#commit_siblings = 5                    # range 1-1000

Apparently its 8.1.8, I thought it was 8.2

The file is 20M, these are the last lines: (the first line continues
unttill ff_26000)
