Re: The postgres server don't work

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
