[pgpool-committers: 2728] pgpool: Fix segfalut that occurs when function is used in FROM clause

[Yugo Nagata]

Fix segfalut that occurs when function is used in FROM clause

When a function is used in FROM, the parser makes a RangeFunction
node whose functions member is a list whose last element is NIL.
This caused segfault in foreach loop in _outListWith().

PRPARE statements in streaming-reaplication mode and INSERT/UPDATE
with SELECT in native-replication mode were affected. For example:

- prepare p as select * from generate_series(1,1);
- insert into tbl select now(), * from generate_series(1,1);
