How to fix it guys

Answer 1

In Windows, search for "services" and search for postgres in the list. Right click and select "Start".

Answer 2

It looks like your postgreql server is not running. You can try to launch it with :

On Linux :

 sudo service postgresql start

On windows : changing XX by your postgresql version run :

 net start postgresql-XX

You can also stop using postgres and specify a sqlite database in your config/database.yml file :

changing this line :

adapter: postgresql

by this line :

adapter: sqlite3

Answer 3

If you are running postgres in a docker image, be sure to map the container port to the host. You can do this with docker run -p 5432:5432 <container-name> or by adding the following to your docker-compose.yml file:

ports:
- 5342:5342

Answer 4

If you are using postgreql this issue is due to not starting a server, so you should start the server, one way to do it is to cd to postgresql bin and start it with pg_ctl , here is an example:

cd "C:\Program Files\PostgreSQL\14\bin"
pg_ctl -D "C:\Program Files\PostgreSQL\14\data" start
