i think an organization trashes old logs for out-of-band reasons - acquiring more disk space requires following an organization's procurement process which imposes tons of friction, or because compliance with applicable regulations requires saving, e.g., emails, for three months and saving them for longer is a legal risk.

Or... because I don't really care what what time Postgres started up 2 years ago.

Old logs may be a privacy liability; and depending on the type of log and the load on the system, the fully loaded cost of keeping logs indefinitely may be too high to justify based on the revenue for a customer (I'm thinking of ISP logs in particular, for example).
