If we can have ALTER TABLE running on heavy workload, why not. I am bit scared by the effect of such reloption, it focus on HINT oriented strategy when I would like to allow a dynamic strategy from the server. This work is not done and may not work, so a reloption is good at least as a backup (and is more in the idea suggested by Tom and others) > > -- > Álvaro Herrera <alvhe...@commandprompt.com> > The PostgreSQL Company - Command Prompt, Inc. > PostgreSQL Replication, Consulting, Custom Development, 24x7 support > -- Cédric Villemain 2ndQuadrant http://2ndQuadrant.fr/ PostgreSQL : Expertise, Formation et Support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
