Thank you for the answer. Does that mean everything on Mac server will be stored in PostgreSQL database but not in their own file system? I am sorry if that was a stupid question. I do not have a Mac mini for my self but one of my client has it.
Little background of the issue which I would like to solve for us:
We devolop software which is used to analyse data. We package PostgreSQL along with the software. One of our client installed our software on mac mini server. When he started the application there was a problem and postgreSQL did not start.
Then he used diskutility and did somthing which solved the problem.
When I was looking for possible troubleshooting options for PostgreSQL I found "PostgreSQL is the default database on Mac OS X Server as of version 10.7. The standard version of Mac OS X includes only the PostgreSQL commandline client utilities." this piece of information.
Then I was confused whether the software is listening to the packaged PostgreSQL or the inbuilt one.
We were also suspecting there could be more problems if it is wrighting the data into inbuilt PostgreSQL.
Thanks in advance.
