Обсуждение: Removing raw data files
Hello, I asked this question a while ago and I didn't get an answer. Perhaps I asked the question in a manner that wasn't clear. I upgraded from 8.1.3 to 8.2.3. I left the 8.1.3 database intact in case I had to revert to it. The 8.2.3 database is running just fine and I'd like to recover the space that the 8.1.3 raw data directories are consuming. Can I just remove the raw data files with rm -rf on the data directory for the 8.1.3 version? This may sound like a silly question but the database I worked with prior to postgres was MS SQL Server. On that platform, you never know when something from the last version is imbedded in the new version. Carol

You can safely remove everything from the previous installation - I'm supposing, your 8.2.x data directory is totally separate? There is no hidden connection between both data directories. You dumped everything into a file, so everything was in that file, then you restored to 8.2.x, so everything is in 8.2.x now.

The cautious sysadmin in me says to set the directory to owner root and perms 000 so it's not accesible. Then if something goes horribly wrong, you've still got the original directory. If not, after a week or two you can delete it knowing nothing is accessing it.
Uh-huh. I like this answer. Will do this and send result. Might be interesting.
