Gaetano, thanks.
My db has only one table (about 29,000 records), so I thought leaving postgreqsql.conf at its defaults would be OK: the params you mention are commented out, so they must be at their defaults, tho I can't tell what the defaults are.
The values on the line commented are the default values.
Are there any docs that talk specificially about how to set these params and what the defaults are (the official docs don't say much)?
Take a look at performance NG, at least is what I use to do.
Regards Gaetano Mendola
