Hmm. Culprit seems to be postgres/postgres@4d82750. I think probably
get_toast_snapshot()for the win.GetOldestSnapshot -> get_toast_snapshot

Are you planning to do a release supporting PG18? That would be one PG18 TODO list item less on my list.
jcflack commentedon Jun 2, 2025
I believe the most recent merged pull request #529 should take care of PG18. A test build from the
REL1_6_STABLEbranch ought to work now.I always have a bit of internal debate about how early to cut the official release. Maybe when there's an 18 release candidate?

RC would be very late. How about now? 18 Beta1 is out, that would also allow people to beta-test pljava on 18. Yes, sometimes features get reverted that might break extensions again, or there might be more changes, but that's not the norm.

Believed resolved in 1.6.10. Sorry for the delay. (On the bright side, also allowed confirming the release works with Java 25.)
