I figured as much, and told our gang that also. Was looking through the release notes a little, need to finish with 4
andlook at 5.

Yeah, trying to figure out how feasible it is for us to do quickly. Ok, we have approval, and will be working on an
upgradedbuild in the morning.

Well, if it’s our schema, 9.6 didn’t care about it, doesn’t mean there wasn’t one though, and I understand that
completely.
So, how do I go about capturing more information for the big brains (you guys) to help figure this out? I have all our
resourcesat mine (and hence your) disposal.

Good, but the previous release of our product was at 9.6, so we’re currently using the pg_upgrade to do that, automated
(storageappliance). Just talking out loud, that switching to 13.5 shouldn’t cause us any upgrade issues other than
figuringout builds and dependencies and some upgrade testing. And a straight re-run with 13.5 on top of the db should
workjust fine. When I talk out loud, I sometimes catch the stupid things I’m missing, and it allows others to point
outthe stupid things I’m missing...
Best,
