I talked to Sybase people about their latest technologies. Many features
that shipped with their latest ASE 15.5 product has been in PostgreSQL
since many years (like functional indexes, etc). :)

One of the things that interested me was parallel recovery feature. They
said that they are keeping separate xlogs for each database, which
speeds ups recovery in case of a crash. It also would increase
performance, since we could write xlogs to separate disks.

Is that doable for PostgreSQL, too?
