[Social-discuss] Question regarding old rows in queue_item

[Steve Revilak]

Hello Social discuss,

I recently inherited a gnusocial instance and just upgraded it from
1.1.x to the current master branch.  I'd like to extend kudos to
whomever wrote upgrade.php; it was very tolerant of being killed and
restarted, which is an extremely nice property for a database upgrade
script.

I've noticed that our queue_item table has a lot of rows where
`claimed` is not NULL, and the claim date is long in the past.  I've
included a set of query output (below) to illustrate this.

Is it safe to delete these rows?

Or to put it a different way, what's the appropriate way to tell
gnusocial "these are old -- just forget about them".  (I went through
the scripts/ directory, but didn't see anything to the effect of
"clean up old queue items").
