Upgraded to 0.19.2

Upgrade itself went OK. Also updated pict-rs to 0.5.1 which performed a metadata update.

I tested this upgrade last Thursday 2024-01-11 but rolled back when outgoing federation didn't work.

Found a fix from matrix.org (thanks to [email protected] and [email protected]) by updating the "updated" column on the instance table.

UPDATE instance SET updated = now() WHERE updated > now() - interval '14 days';

Total downtime was 12 minutes.
