In projectSetProcessor, the `gen` array is not populated until nextInputRow() is called in Next. But, we expected that these generators had been populated in MustBeStreaming which is called before Next() is called. As a result, rows returned streaming value generators were still buffered. I believe this is the main cause of cockroachdb#85630 and other odd behaviour we've seen in the tenant replication tests. Release note: None

Under stress I've gone 5+ mins without a failure I suspect #85866 fixed this and we just forgot to unskip. |
