And here you go as attached. Looking closer, in v10 and older versions,
ALTER INDEX SET STATISTICS is able to work as it is an alias of ALTER
TABLE. The attached patch does not bother generating the ALTER INDEX
queries for v10 and older and feeds queries with empty strings. Perhaps
we should support that case? Or the lack of complains would be an
argument sufficient to care only about v11 and newer versions? I would
tend to think that supporting only v11 and above is enough. Thoughts
are welcome.
