How to configure postgresql DBMS?

Question

PostgreSQL

When trying to connect to the server in postgresql pgadmin4, the following error appears:

could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 2452? could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 2452?

Yesterday it was not, but there were other errors.

How to set up this here ... I did not change any settings, as it was installed and launched.

Answer 1

2452 is not the standard port for postgresql. Either specify one in the postgresql settings, or connect to 5432.
