Dear Jussi, Dear Michael,

thanks for your comments. You are both referring to the main draft
paper, the chapter on PostgreSQL features, I suppose. You are right, I
have to correct the statement on multi-processor support. I put it
better, I hope, in the Informix migration case study (p.18):
"The SUN server uses two SPARC processors. PostgreSQL will make use of
both when separate connections are running in parallel. The DBMS is not
able to spread one connection?s query over both CPUs."

Regards,
Jutta
