[Pgpool-committers] pgpool - pgpool-II: Fix nodeToString() bug.

[User T-ishii]

Log Message:
-----------
Fix nodeToString() bug. example test case:
If nodeToString() is given the parse tree of "insert into r1
values(1,2), (3,4)", it returns "insert into r1 values(1,2),
values(3,4)", which is apparently wrong.
