Bug reference: 16301
Logged by: boli
Email address: boli9301@163.com
PostgreSQL version: 12.2
Operating system: windows 64
Description:

I am in the China. I download the Pgadmin and want to create a server. The
host name is localhost, port is 5432, I also fill other information. Then,
the error is unable to connect server: 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

Just to be clear, did you also download and install the server? Creating a
server in pgAdmin doesn't actually create a new PostgreSQL server, it
create a server profile in pgAdmin that points to a server that is already
running.

Dear David J.
I only download the pgadmin4-4.19-x86.exe
<https://ftp.postgresql.org/pub/pgadmin/pgadmin4/v4.19/windows/pgadmin4-4.19-x86.exe&gt; and
install it. The issue is that it works when I use Pgadmin in UC, Berkeley.

What works or doesn’t work at school is largely immaterial. If you want a
server on your local machine you need to install it. PgAdmin is only a
client.
