I came up with the following patch. What this does is cancel any
ANALYZE started by autovacuum, at the top of ALTER TABLE.
There is a new function relation_openrv_cav(). This is the same as
relation_openrv, except that it will also cancel analyzes. I'm still
wondering if I should merge the two and have a third boolean argument to
specify whether to do the cancel.
Comments?
