Moving PostgreSQL data directory on Windows

[Ottó Havasvölgyi <havasvolgyi.otto@xxxxxxxxx>]

Hello,

I would like to move the data directory to another location. I have done this:
1. Stop PostgreSQL
2. Move data directory
3. Create a PGDATA env. variable to the new location
4. Start PostgreSQL

And it cannot start, because it cannot find postgresql.conf. (in Event log)
What should I do now?

Thanks,
Otto
