This allocation size is close to 2 ^ 64 (which is
18446744073709551616). Whenever I've seen this before, it tended to be
down to a corrupt length word for some variable-width field.
Can you try using pg_dump on any tables associated with the
problematic queries/procedures? That might confirm that this is some
kind of garden variety corruption.
