Re: Moving PostgreSQL data directory on Windows

Hi,

I was just doing the same thing this morning, well somewhat the same;
anyways, what I did was 

1. uninstall Postgres, and run the installation again(don't use the
upgrade.bat), same major version. 
2. on the initial installation window, choose a new data directory by
clicking on browse, point to your new location of data directory (the
directory where you moved the data)
3. make sure you enable the run as service
4. don't initialize cluster db, uncheck it.
5. continue with installation.
6. you should be able to start the service from the services msc.

Regards,


Jonel Rienton

Hello,

Ok. I did not set any security on the machine. Only I have access to it. Now
I have done this:

0. Registry is modified (yesterday)
1. Restart today
2. Modify registry to the old value
3. Start PostgreSQL -> pg_ctl and postmaster are running (they are in the
task list), but no postgres 4. "pg_ctl status" says that neither postmaster
nor postgres are running. No new entry in event log.
5. Stop with "pg_ctl stop" -> it says "Could not send stop signal (PID
3624): no such process".  There is really no such PID.
6. Restart Windows -> the same as before 7. Stop PostgreSQL from the Sart
menu -> it took a half minute, and now only postmaster is running.
8. pg_ctl unregister -N "pgsql-8.0" -> seems it succeeded 9. Register on the
new location 10. Start with "net start "pgsql-8.0"" -> The service could not
be started, no event log entry. Perhaps because a postmaster isrunning.
11. Kill postmaster, I cannot stop it in other way.
12. Start from Start menu and "net start", but nothing happens. The same
message as in step 10.
13. Start from Control panel - Services -> Message: "The service started
then stopped."

Now I really don't know how to start this.
Perhaps reinstaling Postgres is easier.

14. Modified all this with the installer, but PostgreSQL does not start.
15. Backup data directory
16. Uninstall PostgreSQL
17. Install PostgreSQL 8.0.6 (this was installed before), as service, set
the same passwords.
18. Stop PostgreSQL
19. Move the backuped data directory to the location PostgreSQL uses.
20. Start PostgreSQL now, but it does not start this way. :(

What can be done to use my old data? It's not that critical, only tests.

Thanks,
Otto

would want, but it should work. You use pg_ctl unregister to remove the

directory Doing this you won't hvae to reboot..
