Turns out it it's not the replica identity index that's the problem,
it's *another* index with a WHERE clause that evaluates an SQL
function. That's a bug that needs to be fixed. But you might be able to
work around it for now by simplifying your WHERE clauses for the indexes
to not use SQL functions.
