The query to get attribute statistics from a remote server applied the "C" collation to a column of type name without checking the server's version. Since the name type was made collatable in Postgres 12, this could break attribute statistics import if the server was older. Fix by casting the column value to text before collating it if the server is older. Also, fix a typo in the if-test in the same function. Oversights in commit 28972b6fc; the former was reported by Fujii Masao.
