r69235 changed the code to add a number of new entries to page_props, but page_props won't actually be updated until each affected page is re-parsed (e.g. with a null edit). A maintenance script to do whatever needs to be done to cause that to happen more quickly would be nice, per discussion in #wikimedia-tech; we have pages on enwiki that haven't been edited for 4 years (see [[Wikipedia:Dusty articles]]).
