Move WIKI data from one Mountain Lion Server to another

Question

Hi.
I followed the instruction here:
http://support.apple.com/kb/HT5585
Under Copying all wikis from one OS X server to another OS X server, I am not even able to execute:
sudo pg_dump --format=c --compress=9 --blobs --username=collab --file=/tmp/collab.pgdump collab
It gives this error:
pg_dump: [archiver (db)] connection to database "collab" failed: FATAL:  role "collab" does not exist
Any idea?
I just tested it on the productive server as well as a brand new install. Same outcome.
which then I moved the: /Library/Server/Wiki/FileData over but even stop/start, restart, wiki server is running but not able to load content, it's like it's been wiped clean.

Hello Matthew
You're looking in the wrong spot
First things first - make yourself default sudo with sudo -s then you can forget prefixing it all the time.
If you just use pg_dump then it'll take the command from the /var-Directory - that's the wrong version
You have to specify the path for the Socket where the PSQL-Database for the wiki really is located by using the -h-option - it's not the default
that's why you get the error that role collab does not exist since you're connecting to a database in place where the role collab truy isn't part of it.
So - if you'd like to export the wiki-DB us the following and adapt the filename to what you like it to be.
bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/bin/pg_dump -h "/Library/Server/PostgreSQL For Server Services/Socket/" -p 5432 -f /Volumes/USBSTICK/wikidatabase.pgdump -U collab collab
The first block specifies the "not default" pg_dump you'd like to use
The second block (-h "/Library/.....) tells pg_dump where to find the DB
The third block tells pg_dump to use port 5432
The fourth block (-f /Volumes/......) tells pg_dump to place its output into this file
The fifth block (-U collab) tells pg_dump to do this is role collab
The sixth block tells pg_dump from with DB to dump from
In your case extend my provided command with your options --format=c --compress=9 --blobs like this:
bash-3.2# /Applications/Server.app/Contents/ServerRoot/usr/bin/pg_dump -h "/Library/Server/PostgreSQL For Server Services/Socket/" -p 5432 -F c --compress=9 -b -f /Volumes/USBSTICK/wikidatabase.pgdump -U collab collab
BTW- you can connect to the database, of course:
bash-3.2# psql -h "/Library/Server/PostgreSQL For Server Services/Socket/" -p 5432 collab collab
