If you index more than three or four columns you're doing something
wrong. Please explain in more detail why a practical application would
need that many index columns.

Could be.

I'm taking log-file data from a web-server. First I cut and split the
data with a perl script and I send the data to another machine via the
network. To reduce the traffic I have a stored procedure which get the
splitted data. The stored procedure then does a look-up/create in the
reference tables and stores one record which only contain references
to other tables.
Currently I have used 31 parameters for the most important stuff, and
the last parameter is a text-type which I split inside PLPgsql. You
could say that I then only need one parameter to do it all, but that
would use much more CPU time on the server than it does now (I guess).
My system lay-out:
Apache -> log-file
tail -f log-file | log2sql.pl | psql -h othermachine
'psql' use a lot of CPU time so I might use perl-DBI one day.
