We weren't checking the length of the column list in the alias clause of an XMLTABLE or JSON_TABLE function (a "tablefunc" RTE), and it was possible to make the server crash by passing an overly long one. Fix it by throwing an error in that case, like the other places that deal with alias lists. In passing, modify the equivalent test used for join RTEs to look like the other ones, which was different for no apparent reason. This bug came in when XMLTABLE was born in version 10; backpatch to all stable versions. Reported-by: Wang Ke <krking@zju.edu.cn> Discussion: https://postgr.es/m/17480-1c9d73565bb28e90@postgresql.org
