I actually think this is different, at first nowhere is stated that those databases had another page size to start with. Second, the TS is talking about increasing page size, like it was lower before. But I’m quite sure it wasn’t, unless he had some outdated sqlite or did this on purpose: the default page size has been 4096 since 2016. Furthermore, it looks like he fully rebuilt the database. Which in my experience solve most unspecified problems with sqlite and Storj.
Hitherto: I think it had nothing to do with the problem at all, and the rebuilding solved his problem.
Page size itself shouldn’t be an incompatibility issue. Source: Change in Default Page Size in SQLite Version 3.12.0
But don’t know whether there are other unknown/unwanted side effects.
