I am running a software package that uses postgresql 8.1.4 on RHEL to track delta changes. I know very little about postgresql other than how to install it.
My postgresql \var\lib\pgsql\data directory has grown to 57GBs and used up all available disk space on my machine, causing the software to fail.
How can I determine which of the 3 databases my software uses is the large one? Is there a command that will help me determine database size?
This is a critical issue effecting production servers, so immediate assistance would most appreciated.
