PostgreSQL pg_ctl register error under Windows 7

Question

Under Windows 7, PostgreSQL 9.3.2, I'm trying to register as a service a second instance of PostgreSQL on the same server, using a different port number and data directory. The 2nd cluster was successfully created with the initdb command, under C:\Program Files\PostgreSQL\9.3\data2.

When I run the following pg_ctl register command from C:\Program Files\PostgreSQL\9.3\bin, I get an error message:

pg_ctl register -N postgresql9.2_2nd_cluster -U "NT AUTHORITY\NetworkService" -D "C:\Program Files\PostgreSQL\9.3\data2" -S auto -o "-p 5431"

pg_ctl: could not open service manager

I googled this, but without much success.

Answer 1

This error:

pg_ctl: could not open service manager

would suggest that you're probably on a UAC-enabled machine, and you're running in a non-admin console.

When you launch your console from Start->Command Prompt, right click on it and choose "Run as Administrator".
