Hello Mr/Mrs
I hope you are fine and doing well
I have a problem with the postgres server
first my operating system is windows 10 pro
and my postgres version is 13
this problem i have tried to solve it for more than two weeks and
nothing changed
lastly I have formatted the laptop and downloaded only PostgreSQL
program and it worked well for less than a hour then its server broken

Questions and comments inline below.

Define broken?

In other words what does the Postgres log show in the period from when
it ran to when it did not?

the error says in sql shell " could not connect to server: Connection
refused (0x0000274D/10061)
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 5432?"
I changed the port and nothing different
yes this problem is happening regularly but with me nothing solved it

The issue is the below where it could not find the executable. Are you
starting the service as an administrator?

I tried to go to configuration files (the pg_hba.conf ( I added a line
in the last
host all all 0.0.0.0/0 <http://0.0.0.0/0&gt; md5)
and in postgresql.conf file (the listening addresses was already to :"*")

also I when I try to start the server from service tab says
the postgres service cannot restart
it says that "some services stop automatically if they are not in use by
other services or programs
and when I check it in the event viewer there is an error says
 "FATAL: XX000: C:\Program Files\PostgreSQL\13\bin\postgres.exe: could
not locate matching postgres executable LOCATION: getInstallationPaths,
d:\pginstaller_13.auto\postgres.windows-x64\src\backend\postmaster\postmaster.c:1489"

Does this path C:\Program Files\PostgreSQL\13\bin\postgres.exe actually
exist?

and maybe you need to know that after I finish installing the postgre
program I haven't installed the stack builder and when I run the sql
shell for first time there were a problem says "Console code page (437)
differs from Windows code page (1252)
         8-bit characters might not work correctly. See psql reference
         page "Notes for Windows users"

This has to do with the psql client not the server.

and I solved this problem by go to registry
editor/HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/command processor
and there i have entered a new string value called Autorun and its value
is chcp 1252

I hope you’ll help me to fix this problem because I have many tasks I
couldn't do because the postgres problem

thank you for your efforts
my best regards

I mean by broken that when I run psql shell or padding I receive this error
" " could not connect to server: Connection
refused (0x0000274D/10061)
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?"

and about the log file , usually this problem happens after my laptop
turned off or restart
so last line in the log file is "database system is shut down"
and no matter how many times I tried by restart the laptop nothing changes

the ex files are all in their right location , and I tried both ways in
regular running and as administrator and nothing different

yes the postgres.exe is exist there

and about the console code problem ,yes maybe this error is related to the
client but I realized that after I make this solution and make restart to
the laptop , the postgres begins to not working ,maybe this was a
coincidence I don't know

thank you for your efforts

I am not following '...usually this problem happens after my laptop
turned off or restart...'. This would seem to imply that the service
does start sometimes. Is that the case?

regular running and as administrator and nothing different

Do you have an Anti-Virus program running on this machine?

and about the console code problem ,yes maybe this error is related to
the client but I realized that after I make this solution and make
restart to the laptop , the postgres begins to not working ,maybe this
was a coincidence I don't know

Then undo the changes and see what happens? I sort of doubt it is the
issue though.

thank you for your efforts

yes I think the service doesn't even start

I have only the default protection that comes with the operating system

wow the postgres started working!! but the problem came back that talks
about console code " WARNING: Console code page (437) differs from Windows
code page (1252)

8-bit characters might not work correctly. See psql reference
page "Notes for Windows users" for details."

Did you revert the change you made earlier to get it to work?

about console code " WARNING: Console code page (437) differs from
Windows code page (1252)

8-bit characters mightnot work correctly. See psql reference
page "Notes for Windows users"for details."

So follow the instructions here :

https://www.postgresql.org/docs/current/app-psql.html

"
Notes for Windows Users

psql is built as a “console application”. Since the Windows console
windows use a different encoding than the rest of the system, you must
take special care when using 8-bit characters within psql. If psql
detects a problematic console code page, it will warn you at startup. To
change the console code page, two things are necessary:

Set the code page by entering cmd.exe /c chcp 1252. (1252 is a code
page that is appropriate for German; replace it with your value.) If you
are using Cygwin, you can put this command in /etc/profile.

Set the console font to Lucida Console, because the raster font
does not work with the ANSI code page.
"

In the terminal before running psql do:

cmd.exe /c chcp 1252

I don't use Windows anymore so I am going from memory here. In the
Windows menu there should be an entry for Postgres and its sub-programs.
One of those should be named something like psql or database shell.
Click on that, it will run a shell script that prompts you for
connection information and if I remember correctly also takes care of
the above issue.

Such gross changes should not be made to the registry. You changed the
settings of the whole system for the needs of one console. This will affect
many services and console applications.
You need to find a shortcut in the start menu.
"C:\ProgramData\Microsoft\Windows\Start Menu\Programs\PostgreSQL 12\SQL
Shell (psql).lnk"
By the right click, select "Change" and add to the batch file an indication
of the need to change the code page, save.
Here is an example of a standard script:

@echo off
*chcp 1251*
REM Copyright (c) 2012-2020, EnterpriseDB Corporation. All rights reserved
REM PostgreSQL server psql runner script for Windows

SET server=localhost
SET /P server="Server [%server%]: "

SET database=postgres
SET /P database="Database [%database%]: "

SET port=5999
SET /P port="Port [%port%]: "

SET username=postgres
SET /P username="Username [%username%]: "

for /f "delims=" %%a in ('chcp ^|find /c "932"') do @ SET
CLIENTENCODING_JP=%%a
if "%CLIENTENCODING_JP%"=="1" SET PGCLIENTENCODING=SJIS
if "%CLIENTENCODING_JP%"=="1" SET /P PGCLIENTENCODING="Client Encoding
[%PGCLIENTENCODING%]: "

REM Run psql
"C:\Program Files\PostgreSQL\12\bin\psql.exe" -h %server% -U %username% -d
%database% -p %port%

pause

thank you for your efforts
I added chcp 1252 line
but when I try to save the changes . an error pop out says "you don't have
the permission to open this file ,see the owner of the file or an
administrator to obtain permission"
even though I went to properties/security/mylaptopaccount and made it full
control

yes sorry I wrote this sentence before try the solution you offered

yes by deleting the changes (the Autorun)

and thank you so much for your efforts ,I have gone through this solution
before but didn't help me to solve the problem ,when I go to command
prompt as administrator and insert chcp 1252 the command says 1252 is
activated
and changed the font from the properties/font then click apply then open
the sql shell the error still there even though the font look looks
different than before

You need to open the folder containing the file and (you must be an

Open the file in an editor running as an administrator.
OR
Right click on the file "C:\Program
Files\PostgreSQL\12\scripts\runpsql.bat" -> Properties-> Security. Select
the "Users" group, click "Change" and give write access, click apply.
Starting with Windows 10, the "Program Files" folder is not writable for
regular users and administrators, not in administrator mode.
If all this is difficult for you, just copy the file to your desktop, edit
and run, it will be the same.
