Hello,

my backup command for postgres is

/usr/bin/pg_dumpall -o -c -v > /srv/dspace/dumpall.sql

I have carried that with me since DSpace 1.3 or DSpace 1.4. Currently, I use 
DSpace 1.8.

Now, while moving to a new machine, I revisited the section under Architecture 
/ Storage Layer in th Documentation and could not find any hint as to why I had 
used the -o option at all. The oldest version of the docs that I still have 
stored locally is DSpace 1.4.2 and there is no mention of -o either.

Had there ever been a requirement to preserve oids while backing up which has 
been removed meanwhile? Did this option make it into my installation by an 
arbitrary yet stupid inspiration of mine? Should I preserve it since it has 
worked so good all the time or should I skip it to make things clean and 
simple? Any opinion and advice appreciated.

Thanks, Christian
