It is. It's just the stats collector that won't work, and autovacuum which depends on a working stats collector. Otherwise the system is functional.

But it will get broken! Without the autovacuum (and a manual vacuum) a PG installation could run into loss of (very) old data, because of the transaction ID wraparound.

Lossing data is very bad, the solution provided by Robert is really simple. I support Roberts approach.
