Thank you for paying attention to it!
I closed https://commitfest.postgresql.org/43/4280/ as committed.

The confusing message I noted previously:
ERROR:  index row size 8040 exceeds maximum 8152 for index "test_idx"
is not emitted now, although I think it still can be produced for some
other gist indexes. But that's a matter for another day, I suppose.

Best regards,
Alexander
