I'm running postgrSQL 7.2 on a linux Red Hat 8.0
box with 2GB of RAM
When I boot-up the system , this is the TOP
situation:
11:59am up 4 min, 1 user, load average: 0.37, 0.26,
0.11 77 processes: 74
sleeping, 3 running, 0 zombie, 0 stopped CPU states: 0.3% user, 0.7% system, 0.0% nice, 98.8%
idle Mem: 1031020K av, 177808K used, 853212K free, 0K
shrd, 14744K
buff Swap: 2096472K
av,
0K used, 2096472K free
67828K cached After I've done a vacuum , the situation
is:
12:04pm up 8 min, 1 user, load average: 0.22, 0.23,
0.12 78 processes: 76
sleeping, 2 running, 0 zombie, 0 stopped CPU states: 2.5% user, 1.9% system, 0.0% nice, 95.4%
idle Mem: 1031020K av, 1016580K used, 14440K free, 0K

0K used, 2096472K free
833896K cached As you see the memory used by vacuum isn't released anymore? Anyone know
why?
My statement is: vacuumdb --analyze dbname
My pg paramaters on postgresql.conf are:
#
# Shared Memory Size # shared_buffers = 2048 # 2*max_connections, min 16 max_fsm_relations = 100 # min 10, fsm is free space map max_fsm_pages = 10000 # min 1000, fsm is free space map max_locks_per_transaction = 64 # min 10 wal_buffers = 8 # min 4 #
# Non-shared Memory Sizes # sort_mem = 512 # min 32 vacuum_mem = 8192 # min 1024 Did anyone know why this happend?
