You *still* haven't defined what you mean by "fails". We can't help
you effectively with such tiny dribs and drabs of information.
At the very least I'd like to see the whole query, because the
fragment you've shown us does not reveal what ekey is or why you
think the system should believe that it is or is not zero.
But it's also unclear why that should matter.
Having said that ... if the statement is being executed with a cached
plan (via a named statement, or PREPARE, or inside plpgsql) then
maybe the problem occurs if the plan switches from custom to generic?
If so, messing with the plan_cache_mode setting might provide a
workaround.
