OK, thanks.
Patch appears to work cleanly now.
I'm wondering now about automatically inferring "recheck_on_update =
true" for certain common datatype/operators. It doesn't need to be an
exhaustive list, but it would be useful if we detected the main use
case of
(JSONB datatype column)->>CONSTANT
Seems like we could do a test to see if the index function is
FUNCTION(COLUMNNAME, CONSTANTs...)
{JSONB, ->>} or
{jsonb_object_field_text(Columnname, Constant)}
{substring(Columname, Constants...)}
It would be a shame if people had to remember to use this for the
common and obvious cases.
