Обсуждение: Problem with bacula and 8.3/8.4

Hi all,

I've tried, in various combinations, bacula (2.4, 3.0) and pgsql 8.4
and 8.3 in an upgrade attempt.  Whichever combo I try I get the
following error:

19-Aug 02:24 bacula-dir JobId 1951: Fatal error: sql_create.c:789
Fill Path table Query failed: INSERT INTO Path (Path) SELECT a.Path
FROM (SELECT DISTINCT Path FROM batch) AS a WHERE NOT EXISTS (SELECT
Path FROM Path WHERE Path = a.Path) : ERR=ERROR:  array size exceeds
the maximum allowed (268435455)

Batch is a temp table so I tried bumping temp_buffers up to 268MB but
I still got the error.  Anything I else I should try before I
rollback the upgrade?

tia,
arturo

That's odd. Where's the array? Subqueries shouldn't result in arrays in
any way, no?

On my Bacula install there are no triggers on the `path' table and it's
a very simple table:

                           Table "public.path"
 Column |  Type   |                       Modifiers
--------+---------+-------------------------------------------------------
 pathid | integer | not null default nextval('path_pathid_seq'::regclass)
 path   | text    | not null
Indexes:
    "path_pkey" PRIMARY KEY, btree (pathid)
    "path_name_idx" btree (path)


so I'm a bit puzzled. Just to see, try expressing the query in two steps:

SELECT path INTO TEMPORARY TABLE batch_path
FROM  batch GROUP BY path;

INSERT INTO Path (Path)
SELECT batch_path.Path
FROM batch_path AS a
WHERE NOT EXISTS (SELECT 1 FROM Path WHERE Path = a.Path);

Looks like a bad build so far.  I was upgrading to 3.0/8.4 and tried
to build
everything universal (on Mac) to future-proof the upgrade.  I built
just a native
binary and it seems to work better.
