That's quite odd.
But it looks like the data here is corrupt from offset 1d5c for the next
64 bytes (+/- 4 bytes, maybe, but much more likely to be exactly 64).
That's not something I recall seeing before, but some kind of hardware
corruption issue couldn't be ruled out. I don't suppose you have data
checksums enabled?
The "cache lookup failed" error is caused by the fact that the column
_after_ dattablespace, i.e. datacl, is also corrupt (the database must
have had a non-null ACL with an additional grant to exactly one role
going by the layout of records).

That's not really weird - the pg_database rows can get updated, e.g.
from grant/revoke, and autovacuum usually won't kick in for a long time
because the table is so tiny. So some number of old dead row versions is
expected - likewise for your own db.
