Commit dae761a87ed modified brin_page_items() to return the new "empty" flag for each BRIN range. But the new output parameter was added in the middle, which may cause crashes when using the new binary with old function definition. The ideal solution would be to introduce API versioning similar to what pg_stat_statements does, but it's too late for that as PG17 was already released (so we can't introduce a new extension version). We could do something similar in brin_page_items() by checking the number of output columns (and ignoring the new flag), but it doesn't seem very nice. Instead, simply error out and suggest updating the extension to the latest version. pageinspect is a superuser-only extension, and there's not much reason to run an older version. Moreover, there's a precedent for this approach in 691e8b2e18. Reported by Ľuboslav Špilák, investigation and patch by me. Backpatch to 17, same as dae761a87ed.
