Been a good two or three weeks without crashing. Right in the middle of a daily backup, too. Would've been just three hours or downtime or so if not for this shit:

>** (Postgrex.Error) ERROR XX000 (internal_error) could not open file "base/79951/5181063.7" (target block 21102592): previous segment is only 55208 blocks

Thankfully, pg_repack seems to have taken care of that. Same shit on salon, will fix it later.
