Hello, at Prato PgDay in 2007 I remember hearing in a speech about a (then yet to come) "seqscan piggyback" feature, allowing concurrent sequential scans to use the same disk reads. I've now googled for info about this feature, but I found nothing conclusive (e.g. [1], [2] - which I don't know where is linked). So I'd like to know: is this feature currently implemented (I'm specifically interested in PG 8.3)? Is there any prerequisite needed to benefit from it (config setting, query characteristic, etc.)? Is there any feedback showing the feature kicking in (e.g. an explain analyze output, log, etc.)? Thank you very much. -- Daniele [1] http://wordpress.metro.cx/2008/02/24/postgresql-83/ [2] http://www.postgresql.org/about/featuredetail/feature.26 -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
