Allright, I updated the PR with your suggested changes. If you could give me 
one last confirmation that this is ok, I can push it.

>          Components: jdbc-adapter

> Rendering a VALUES relnode to e.g. PostgreSQL will produce \{{FROM 
> (VALUES((1))) AS t(col_alias)}} where "t" is a static alias. When e.g. 
> joining with such a VALUES, the RelToSqlConverter tries to re-alias this with 
> a unique alias, but fails because it produces \{{FROM (VALUES((1))) AS 
> t(col_alias) AS newAlias}}.
> The fix is to replace the static table alias instead.
