I have PostgreSQL 9.4 installed on a dual-boot machine (both on Win 7 and Ubuntu 14.10). The two systems share a drive which includes a PSQL database directory which was created under Windows. Obviously the PSQL installations are system-specific, and they also happen to be on different partitions. The drive is automatically mounted under Linux and given full read/write/execute access.

I would like to know if it is possible to share the structure and data between the two systems without duplicating and/or having to copy everything each time I load a new OS. Effectively, I would like all the data to be available to Ubuntu when it is created in Windows, and vice versa.

**Is this possible, and if so, how would one set this up from Linux assuming all the data was originally generated under Windows?**
