I'm sitting in Alexey Ermakov's talk and he just said that the command in $SUBJECT is not documented ... do we need a separate blurb about it somewhere?
I just tried it and it does do something useful, at least for expression indexes, since we collect stats for those. This is news to me. There's a small issue that the column names for them are rather awful, but since they are unique there's not actually anything you can't do. Note that it's allowed to change the stats target of non-expression index columns too, but that doesn't seem to have any useful effect. -- Álvaro Herrera Peñalolén, Chile -- Sent via pgsql-docs mailing list (pgsql-docs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-docs
