Hello,
I would like to move the data directory to another location. I have done thi
s:
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

Dumb question, but are you sure you exported the PGDATA variable? Is
it pointing to the directory that actually contains postgresql.conf?
If you still have problems, post the exact error message that appears
in the logs.

Are you running it as a service:? If so you need to reconfigure the service.
Unfortunatly,the only way to do this is using regedit. Go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControl
Set\Services\pgsql-8.1
Open the value "ImagePath" and change the data directory.

Duh, I didn't read the subject line and assumed it was on Unix.

Is this documented anywhere? Certainly our SGML manuals don't talk
about anything except the Unix case. Perhaps there needs to be a
chapter in the Server Administration section about managing a Windows
PG server. Or is all that in the installer docs?

- Magnus,
It's a service, and it is 8.0.6. I have fixed the registry to this
value: "C:\Program Files\PostgreSQL\8.0\bin\pg_ctl.exe" runservice -N
"pgsql-8.0" -D "E:\PostgreSQL\data\"
The service does not start.
This new directory definetely exists. But now there is no Event log
entry about the error. The log file says nothing because it is in the
data/pg_log directory.
Thanks,
Otto

- Ok, two things:
First, when using this method, yo uhave to reboot after editing the registry
. If you didn't do that, then that's your problem. Sorry, forgot to mention
that. If not, then looking at permissions as Rodrigo suggested is the next s
tep.
Second, there is of course a nicer way of doing this than editing the regist
ry, that I compleetley forgot about. It's still not as nice as you would wan
t, but it should work. You use pg_ctl unregister to remove the service, and
then pg_ctl register to reg
ister a new one with the new data directory. Doing this you won't hvae to re
boot.
Perhaps this is something we should add to pg_ctl for 8.2? "pg_ctl reconfigu
re" or something like that? What do others think?

- 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

- 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.

Jonel Rienton
