I've tidied up my previous explanation into a wiki page, since it'll
come up again. Your comments and suggestions would be appreciated:
http://wiki.postgresql.org/wiki/Prioritizing_databases_by_separating_into_multiple_clusters
I've also added a general explanation of the issues with prioritizing
users/queries/connections/databases:
http://wiki.postgresql.org/wiki/Priorities
Both pages are very much draft quality. Comments, edits, etc would be
most welcome.
