The documentation https://www.postgresql.org/docs/13/server-start.html offers this command:
$ postgres -D /usr/local/pgsql/data
But with this command I get the following error:
Running the PostgreSQL server by a user with administrator rights is not allowed. The server must be started with an unprivileged user to prevent any security issue on the server. See the documentation for more information on running the server clean.*
You should be using pg_ctl to start the Server - that ensures that the administrator privileges are dropped during startup.
Something like:
pg_ctl -D c:/Data/PostgresData start
You can register Postgres a Windows service using pg_ctl
The parameters are documented in the manual
pg_ctl register -N postgresql-13 -D c:/Data/PostgresData
That must be done with Administrator privileges.
By default the service is set to automatic start, you can disable that if you want. Then you can start it manually using:
net start postgresql-13
(Again with a privileged Administrator account)
pg_ctrl register ... as explained here$pg_ctl -D "C:\Program Files\PostgreSQL\13\data" option are working now. After launching the command $pg_ctl -D "C:\Program Files\PostgreSQL\13\data" start, the services.msc shows that postgresql-x64-13 - PostgreSQL server 13 is running.
