GAUSS-00191: "recursive query '%s' column %d has collation '%s' in non-recursive term but collation '%s' overall"

SQLSTATE: 42P21

Description: The character set of the column in the recursive query is inconsistent with that of the column in the non-recursive query.

Solution: Convert the output character set of the non-recursive query to that of the recursive query.

postgres=# WITH RECURSIVE foo(x) AS
postgres-#    (SELECT x FROM (VALUES('a' COLLATE "C"),('b')) t(x)
postgres(#    UNION ALL
postgres(#    SELECT (x || 'c') COLLATE "POSIX" FROM foo WHERE length(x) < 10)
postgres-# SELECT * FROM foo;
ERROR:  recursive query "foo" column 1 has collation "C" in non-recursive term but collation "POSIX" overall
LINE 2:    (SELECT x FROM (VALUES('a' COLLATE "C"),('b')) t(x)
                   ^
