Postgres will fail to start if they're actually used. I think there are some 
functions to figure out which ones are used but I suppose you could just move 
them to e.g. /var/tmp and tehn move them back one by one starting from newest 
until it starts.

Not really, I know that for e.g. deletions, a WAL stores the entire old row, 
and the entire new row. You could run a bunch of deletes and inserts and make 
it grow big, that's how yours could get that way. The issue though is that 
posgres is largely self-tuning, and normally that would gradually go down to 
max_wal_size.
