问题
First I use homebrew and install postgresql and I get this success message:
==> Summary 🍺 /usr/local/Cellar/postgresql/9.2.2: 2819 files, 39M, built in 68 seconds
Then I need to run this command:
initdb `brew --prefix`/var/postgres -E utf8
But this is the message I get: What should I do with this? Also running on OSX 10.8.2
The files belonging to this database system will be owned by user "JonyIve". This user must also own the server process.
The database cluster will be initialized with locale "en_US.UTF-8". The default text search configuration will be set to "english".
initdb: directory "/usr/local/var/postgres" exists but is not empty If you want to create a new database system, either remove or empty the directory "/usr/local/var/postgres" or run initdb with an argument other than "/usr/local/var/postgres".
回答1:
Assuming this is a new installation and not a re-installation I think solving your problem is as simple as:
initdb `brew --prefix`/var/postgres/data -E utf8
Typically the data directory is called "data' and is underneath the postgresql home directory. this allows for the possibility of sharing log file access and the like.

If you know that you can do this without breaking anything, another option is always just to remove the directory as per the message
remove or empty the directory "/usr/local/var/postgres"
Via
rm -rf /usr/local/var/postgres
