[SQL] postgres 8 data directory other then default?

[Joel Fradkin]

I am trying to use a different drive for the data. I have edited postgres.conf to point to the new location, but I get the error /pgdata/PG_VERSION is missing. Do I have to do a initdb? When I try an initdb it says it is not empty. (has lost and found folder in it). Fedora Core 3 linux. I was able to do an init db if I create a folder called data in the pgdata, but I was not sure if it then would use that folder for all the files (I just want my data to be there). I also want to move my wal files to the /wal drives once I get it to start using pgdata drive for data.   I got some info on this 0) backup your data 1) stop postmaster and verify. 2) cd $PGDATA; mv pg_xlog original_pg_xlog; ln -s /wal pg_xlog; cp original_pg_xlog/* pg_xlog 3) start postmaster and confirm correct startup in log files.   Will this work? I am guessing this info would be in the var/lib folder not the /pgdata folder? Thanks in advance and sorry for asking so many dumb newb questions. Least this time the install of 8 went super smooth, just went to the postgres site and got the rpm’s (Since I did not install 7 with the OS it asked for the fedora cd’s a few times but all rpm’s went ok).   On the 8.1 files which are in tar files do I need to get those as well to get to 8.1 if so what is the procedure other then copying the files to my system (I have the .tar.bz)     Joel Fradkin   Wazagua, Inc. 2520 Trailmate Dr Sarasota, Florida 34243 Tel.  941-753-7111 ext 305   [EMAIL PROTECTED] www.wazagua.com Powered by Wazagua Providing you with the latest Web-based technology & advanced tools. © 2004.
