PostgreSQL version : 6.4.2

Compiler used : Sunpro cc

Hardware:
---------

Versions of other tools:

Problem Description:
--------------------
In psql, if a list of entries in an IN ( ) statement is
split across several lines, missing commas are not flagged as errors,
but the entries immediately before and after the missing comma
are ignored

--------------------------------------------------------------------------

Test Case:
----------
The following sql shows the problem. Note the missing comma between
the 'c' and 'd' lines in the IN( ) clause. The query
should return no rows.

drop table test;

create table test ( s text );

insert into test values ( 'a' );
insert into test values ( 'b' );
insert into test values ( 'c' );
insert into test values ( 'd' );
insert into test values ( 'e' );

select
s
from
test
where
s not in (
'a',
'b',
'c'
'd',
'e'
)
order by s
;
