How to use the postgres db on the windows-latest agent used in the azure pipeline? - postgresql

Question

I have a java maven project that I am building with an azure pipeline with as host "windows-latest" as it contains the correct java 13 version. However, for the integration tests, I need a postgres db and the "windows-latest" agent contains a postgres db, see: link. But how can I use this? I tried to use it by including it's serviceName in the Maven task as service:
services:
postgres: postgresql-x64-13
But then I get the error it can not find a service by that name.
I tried defining the db properties through env settings (see yml below), and then it shows the error:
Caused by: java.net.ConnectException: Connection refused
I also tried running it through a script task through the docker-compose.yml in the root of the project that I use during development, but docker-compose throws an error saying it can't find the compose file, I also doubt this the correct way.
So can I use the postgres db on the windows agent? and how?

In Azure Devops Windows agen, the postgresql is disabled/stop by default.
Here is the configuration doc.
Property Value
ServiceName postgresql-x64-13
Version 13.2
ServiceStatus Stopped
ServiceStartType Disabled
You could try the following command to start the postgresql.
"C:\Program Files\PostgreSQL\13\bin\pg_ctl.exe" start -D "C:\Program Files\PostgreSQL\13\data" -w
