As a first step, before relaunching the query with a new plan I would be happy to be able to get information about sql queries having wrong estimates. Maybe thoses SQL queries could be collected using something similar to "auto_explain" module (tracing finished or cancelled queries). If the "corrected plan" taking into account real cardinalities was proposed (with some advices on how to get it) it would be a great tuning adviser ;o) -- Sent from: http://www.postgresql-archive.org/PostgreSQL-performance-f2050081.html -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
