Putting a database on Gluster is a horrible idea in any case. But no,
PostgreSQL does not have Gluster-specific support.
I'm actually trying to think of a use case where it would make sense; I
suppose a large data warehouse could theoretically see some sequential read
improvements from a scale-out cluster file system. But you could only have one
client node accessing it.
