Обсуждение: Need a help - Performance issues

I am currently looking at some performance issues. Our product uses the postgres as the backend
and it uses a huge storage space.

Is there a script available, which does the following:


1. When you point it to a postgres installation, -> 1.the script first    identifies what platform
(solaris-sparc/solarisx86/ Niagara) it is   running on,
 
2. walks through all known tuning parameters (in /etc/system and   postgresql.conf) on the system
3. lists out what parameters are optimal/suboptimal for that   platform, and makes recommendations.
4. identifies when the last vaccumdb /fullvacuum (and other such   database health maintenance commands) were run
5. comments about the growth of certain tables/databases


If any body has the scripts or can give some links which could be useful for our group.



Thanks
Dhanaraj

I thought that's why people still have DBAs ;}

There is/was a pg_autotune project, but it was pretty rudamentary and
didn't work very well when I tried it circa 2001. Your best bet is
probably to either do a lot of research, or hire a consultant.
