I upgraded to mavericks and had some trouble installing/compiling new gems so I reinstalled xcode and did a brew update and upgrade. Gems work now, and even postgres continued to work for a while until a recent reboot. Now postgres seems to be having issues.
postgres:
postgres does not know where to find the server configuration file.
You must specify the --config-file or -D invocation option or set the PGDATA environment variable.
brew info postgres:
postgresql: stable 9.3.2 (bottled)

Poured from bottle
postgres -D /usr/local/var/postgres:
FATAL: database files are incompatible with server
DETAIL: The data directory was initialized by PostgreSQL version 9.2, which is not compatible with this version 9.3.2.
What should I do now to get my database working again?
