Hm, it looks like some bright soul at Hibernate decided to depend on an
undocumented internal function :-(

Hibernate. As a short term workaround you could manually create the
function using the 8.0 definition, which is
/* This returns the integers from 1 to INDEX_MAX_KEYS/FUNC_MAX_ARGS */
CREATE FUNCTION information_schema._pg_keypositions() RETURNS SETOF integer
LANGUAGE sql
IMMUTABLE
AS 'select g.s
from generate_series(1,current_setting(''max_index_keys'')::int,1)
as g(s)';
Note that one reason this went away in 8.1 is that there no longer is a
hard upper limit to the number of function arguments, so depending on
what Hibernate is expecting it to do, you might have some issues ...
