Hello, I have created new tablespace on a new drive yesterday and modified some of existing databases to use this tablespace as default, like this:
ALTER DATABASE xxx
SET default_tablespace = 'vol4';
So, this command did not physically move any existing tables/indices on the database xxx, but all new objects are currently being created on this tablespace (this was expected).
Please note, I also altered "template1" database to use new volume, to ensure all new databases will be created there by default.
ALTER DATABASE template1
SET default_tablespace = 'vol4'; However, I have not yet modified postgresql.conf, and our settings for default_tablespace and temp_tablespaces still set to use "vol3", because I was planning to leave some of databases
out of vol4 (newer tablespace), since I did NOT altered their default_tablespace, and it was previously set to vol3.
Today, checking which tables were created where, I noticed, that all new tables, including tables from those databases which I did not alter to use new volume as default_tablespace,
have been created on new volume 4. If I select from pg_database, I can see all my user databases have default_tablespace as vol4 (newer tablespace), even though I did not modify it. So, my question is, could altering "template1" database change default tablespace
for all existing databases on a server???
PS. I could not make a mistake altering all, since I scripted my commands before, eliminating some of databases, and I do not see it in my script. Any thoughts?
Thank you
