In this case it will be possible to get this error even if you're just running
a single SELECT query -- and that's the *only* query in the database at all.

A vacuum being replayed -- even in a different database -- could trigger the
error. Or with the btree split issue, a data load -- again even in a different
database -- would be quite likely cause your SELECT to be killed.
