calibredb check-library command
Does the calibredb check-library command 'vacuum' the database ?

If not could it?

It doesn't. You want to vacuum the db from the command line, just do:

calibre-debug -c "from calibre.library import db; db().new_api.vacuum()"

For us laypersons, what does 'vacuum the database' actually do?

Not the answer I anticipated, I've always assumed it was same as Library Maintenance. Good job I checked I was going to suggest to someone they could use the calibredb check library command to do the vacuuming

So do I need to add calibre-debug lines to to my weekly housekeeping script, or will the next version of calibredb check-library do it for me?

Might as well ask: does calibredb check-library do the database integrity check (the step between the vacuum and the consistency check in the GUI version) ? If not could it?

The next release will do it and the the vacuum is the database integrity check.
