In an attempt to get a hackfix for

whenlooking at pg_locks, the only pid which will have virtualxid = '1/1' and virtualtransaction = '-1/0' will be the
bgwriter.That seems correct on all my dbs, but that's hardly a definitive test.

Just stumbled upon the same issue. You got no reply here... maybe it's
worth contacting -hackers about it. I've tried googling around and
found no discussion about the bgwriter keeping that lock, except your
message.

Good luck, cheers!
