Hi Everybody,

Is it possible to move the directory associated to a tablespace and
update that information in the postgres cluster?

I was expecting something like : ALTER TABLESPACE LOCATION "C:\..." but
found no such usage.  Looking it up in the documentation I found that on
linux one could

- shutdown postgres instance

- move the directory

- fix the symbolic link in $PGDATA/pg_tblspc

- start postgres instance

- update the pg_tablespace entry

 

I am running postgres 8.3.0 on windows 2003 sp2, according to wikipedia
windows "symbolic links" have been implemented on xp only, so my
platform would not have them. Altering the pg_tablespace it's self and
moving the directory does not work, I get the following error: could not
create directory "pg_tblspc/16439/111451"; No such file or directory.

 

Questions:

1.	is it possible to move a tablespace ?
2.	how does the instance keep track of the pg_tblspc contents if
there are no symbolic links on windows?

 

Thank you,

Sincerely,

Kasia
