Обсуждение: indexing arrays in pgaccess's query interface is failing

Hi there, I am having some difficulties with using arrays in pgaccess 
relating to arrays.

Here is an example schema:

CREATE TABLE arraykeys (   akID int,   akName varchar(12),   PRIMARY KEY(akID)
);

CREATE TABLE items (   itID serial,   itProperties bool[],   PRIMARY KEY(itID)
);

--.. And some Data

INSERT INTO arraykeys VALUES (1,'Active');
INSERT INTO arraykeys VALUES (2,'Overdue');
INSERT INTO arraykeys VALUES (3,'Local');

INSERT INTO items (itProperties) VALUES ( '{1,0,1}');
INSERT INTO items (itProperties) VALUES ( '{0,1,1}');



--.. And now the query that I am having problems with.

SELECT itID, itProperties[akID], akName
FROM items, arraykeys;



In the readline client psql, the above select statement works perfectly
scratch-# FROM items, arraykeys; itid | itproperties | akname
------+--------------+---------    1 | t            | Active    1 | f            | Overdue    1 | t            | Local
 2 | f            | Active    2 | t            | Overdue    2 | t            | Local
 
(6 rows)


However

In pgaccess,
when I try to execute the same query in query builder,
I get the tcl error dialogue:
Error: invalid command name "akID"


Is there an alternate way indexing arrays in queries that I should be 
using?
Or is pgaccess just not suitable for this class of queries!

Someone isn't quoting the query string correctly on the Tcl side ---
[akID] is Tclese for command substitution.  Sounds like pgaccess expects
the user to quote command punctuation characters that should be passed
through.  Not sure if that should be regarded as a bug or a feature.
It could be considered a feature that you can enter SQL commands with
Tcl command substitution performed on them, but it's something that
would confuse non-Tcl-users a lot.

Got the message!

I'll fix the Query builder to quote []'s!
