I tried to install latest PostgreSql on plain Debian using instructions from
I added line described there to sources and tried

How to install it ?

shows that this package exists.
There is also postgresql 8.4 installed.
How to uninstall postgresql 8.4 before installing debian ?

Adrian,
thank you. I'm sorry for stupid mistake.
I uninstalled 8.4. Trying to install 9.1 now returns

How to fix this ?
This is fresh OS install, only Postgresql server will run in this virtual
maschine.

From below it would seem it is still around.
Thank you.
After adding -t switch to apt-get I was able to install 9.1.
To start it I invoked /etc/init.d/postgresql manually.
How to force it to start after server is rebooted automatically ?
free -g returns
total used free shared buffers cached
Mem: 2 0 2 0 0 0
-/+ buffers/cache: 0 2
Swap: 3 0 3
Which parameters in postgresql.conf needs to be changed to work it as fast
as posssible ? This is dedicated server.

IIRC, when you install it via apt-get it should be set to start automatically - I could be wrong, it's been a while. To check whether this is the case, look in the appropriate /etc/rc*.d directory for the runlevel you're using, and see if there is an "S...." symlink to /etc/init.d/postgresql-9.1 (or something like that) in there.

Thank you. There are S18postgresql symlinks in may rc?.d directories. They seems to be version independent so hopefully server is started on boot. Should shared_buffers and other values changed from installations defaults in postgresql.conf file to increase performance ? How to run enterprice db tuner or other utility to chenge them automatically ? Virtual machine seems to have 2 GB of ram. Andrus.

This is dedicated server. The ones marked "greased lightning":) Sorry, could not resist.

Adrian, >For tuning tips a good start is: >http://wiki.postgresql.org/wiki/Performance_Optimization >In particular: >http://wiki.postgresql.org/wiki/Tuning_Your_PostgreSQL_Server >For books take a look at: >http://www.postgresql.org/docs/books/ thank you very much. Reading them requires lot of time. I'm looking for quick optimization for 2 GB RAM. postgresql.conf contains shared_buffers = 24MB # min 128kB #temp_buffers = 8MB # min 800kB #max_prepared_transactions = 0 # zero disables the feature #work_mem = 1MB # min 64kB #maintenance_work_mem = 16MB # min 1MB #max_stack_depth = 2MB # min 100kB Probably only few settings like shared_buffers needs adjusting for 2 gb In windows I use enterpicedb tuning wizard which does this automatically. Maybe something works in Debian also. Or this there quick guide how to change most important settings. Andrus.

I tried # sysctl -w kernel.shmmax=419430400 kernel.shmmax = 419430400 # sysctl -n kernel.shmmax 419430400 according to http://www.postgresql.org/docs/current/static/kernel-resources.html this value should be written to /etc/sysctl.conf I opened /etc/sysctl.conf but it does not contain this value. How to make this setting persistent ? Andrus.

Just add them to the bottom then run sudo sysctl -p to make them take effect. btw, the standard way to control rc stuff is update-rc.d Odd name but it's pretty easy, just look up the man page.
Scott, Thank you. >Just add them to the bottom then run >sudo sysctl -p >to make them take effect. It seems that if this value is greater than RAM, linux kerner silently uses max possible value. Linuxes are used mostly to run PostgreSql only but ram may vary depending on virtual maschine configuration at runtime. Is it reasonable to use large value, eq. 8GB as SHMMAX in sysctl.conf file always ? In this case root and SSH access to server is not required if RAM amount changes. This simplifies server administration. Only postgresql.conf needs changed which can be done from 5432 port using pgAdmin. >btw, the standard way to control rc stuff is update-rc.d Odd name but >it's pretty easy, just look up the man page. Debian seems to require update-rc.d and Centos chkconfig How to use single command for every distro ? "/etc/init.d/postgresql start" works in all distros. Adding to postgresql to startup requires different commands in different distros ?! Andrus
