Problems with PostGreSQL and Windows 2003 - Mailing list pgsql-general

Hello,



I'm having serious problems with PostGreSQL and Windows Server 2003
Enterprise Edition. The PostgreSQL Server doesn't start if I set the shared
buffers higher than 1GB. All my programs can use only 3 GB of RAM and I have 8GB
of RAM.
When I monitor the processes I can see that PostGreSQL allocs only 700 MB of
memory, and
my application 2GB. Total: 3GB.

When I try to execute a query in a table about 4 milion registers, my
application crashes with an error message  "Out of memory" or
"invalid  sql statement". But the sql statement is ok - if I execute it
in a table with less registers, it works and it is very simple.

My program was made in Delphi 2006, and I use ADO via ODBC to connect to
PostGreSQL.


The configuration:

PostGreSQL 8.2.5
O.S: Windows Server 2003 Enterprise Edition
     Service Pack 2

Computer:
dual quad core Intel(R) Xeon(R) CPU E5345 @ 2.33GHz
8GB of RAM
Physical Address Extension
3 HDs in RAID-5


My boot.ini:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows Server 2003, Enterprise"
/fastdetect /PAE   /NoExecute=OptOut /3GB


PostGreSQL.conf:

The structure of my table:

CREATE TABLE "public"."fato_financeiro" (
  "CODCLI" VARCHAR(6),
  "PREST" VARCHAR(4) NOT NULL,
  "NUMTRANSVENDA" VARCHAR(10) NOT NULL,
  "RECNUM" VARCHAR(8) NOT NULL,
  "CODFORNEC" VARCHAR(8),
  "TIPO" VARCHAR(2),
  "NUMDOC" VARCHAR(10),
  "PREST_1" VARCHAR(4),
  "VALOR" DOUBLE PRECISION,
  "DTEMISSAO" TIMESTAMP WITH TIME ZONE,
  "DTVENC" TIMESTAMP WITH TIME ZONE,
  "DTPAG" TIMESTAMP WITH TIME ZONE,
  "VPAGO" DOUBLE PRECISION,
  "PAGO_PAG" VARCHAR(9),
  "ATRASADO" VARCHAR(3),
  CONSTRAINT "fato_financeiro_idx" PRIMARY KEY("PREST", "NUMTRANSVENDA", "RECNUM")
) WITHOUT OIDS;


SQL statement:

select
fato_financeiro."TIPO",
fato_financeiro."NUMDOC",
fato_financeiro."PREST",
fato_financeiro."NUMDOC",
fato_financeiro."DTVENC",
fato_financeiro."DTPAG",
