I don't think that's a bug.

A parenthesis after with_query_name introduces the list of column
names for the WITH-query, and it complains that there is no comma
or closing parenthesis after "insert".

[HACKERS] potential bug in error message in with clause

[Szymon Guz]

Hi,
today on IRC there was a strange problem shown. The small working example
looks like this:

x=# with x as (insert into a(t) values('1') returning *) select * from x;
 t
---
 1
(1 row)

x=# with x (insert into a(t) values('1') returning *) select * from x;
ERROR:  syntax error at or near "into"
LINE 1: with x (insert into a(t) values('1') returning *) select * f...
   ^

The initial code was run on 9.2; I've checked that on 9.4devel.

The error message is really not useful, as there is missing "as" after
"with x". There is no problem with "into".

regards
Szymon
