Subject: Don't force creation of the FSM on searches. It will still be created
X-Git-Tag: recoveryinfrav9~276
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=1ebc4f75391140c5758f5b690688178f244dcc1b;p=users%2Fsimon%2Fpostgres.git

Don't force creation of the FSM on searches. It will still be created
as soon as the first page fills up, and is marked as (almost) full,
though.
