Since the configuration options on the nginx side already exist in the
sample config, there's no need to tell users to copy-paste those
settings in again.
The /var/tmp directory is not mounted as tmpfs unlike /tmp which is
mounted as such on some distros like Fedora or Arch. Since there isn't
really a benefit to having the cache on tmpfs, this change should allow
for a larger cache if needed without worrying about running out of RAM.
Pruning can go on for a long time; give admins some insight into that
something is happening to make it less frustrating and to make it easier
which part of the process is stalled should this happen.
Again most of the changes are merely reindents;
review with whitespace changes hidden recommended.
May sometimes be helpful to get more predictable runtime
than just with an age-based limit.
The subquery for the non-keep-threads path is required
since delte_all does not directly accept limit().
Again most of the diff is just adjusting indentation, best
hide whitespace-only changes with git diff -w or similar.
This gives feedback when to stop rerunning limited batches.
Most of the diff is just adjusting indentation; best reviewed

This part of pruning can be very expensive and bog down the whole
instance to an unusable sate for a long time. It can thus be desireable
to split it from prune_objects and run it on its own in smaller limited batches.
If the batches are smaller enough and spaced out a bit, it may even be possible
to avoid any downtime. If not, the limit can still help to at least make the
downtime duration somewhat more predictable.
Applying works fine with a 20220220135625 version, but it won’t be
rolled back in the right order. Fortunately this action is idempotent
so we can just rename and reapply it with a new id.
To also not break large-scale rollbacks past 2022 for anyone
who already applied it with the old id, keep a stub migration.
This promotes and expands our existing optional migration.
Based on usage statistics from several instances, see:
AkkomaGang/akkoma#764
activities_hosts is now retained after all since it’s essential
for the "instance" query parameter of *oma’s public timeline to
reliably work in a reasonable amount of time. (Although akkoma-fe has
no support for this feature and apparently barely anyone uses it.)
activities_actor_index was already dropped before in
20221211234352_remove_unused_indices; no need to drop it again.
Birthday indices were introduced in pleroma starting with
20220116183110_add_birthday_to_users which is past the
last common migration 20210416051708.
