Greetings,
Would it make sense for vacuum to keep a list of 'last vacuumed' or
similar so that it doesn't vacuum a table which hasn't changed since
the last time it was vacuum'd? Seems to me that would be a pretty
simple optimization which would help out alot on systems which have
both a large set of tables which are relatively static and data which
changes a great deal. This is especially true for vacuum full which
also locks the table.
Thoughts?
Thanks,
Stephen
