* [PATCH] Add pg_tablespace_avail() functions

This exposes the f_avail value from statvfs() on tablespace directories
on the SQL level, allowing monitoring of free disk space from within the
server. On windows, GetDiskFreeSpaceEx() is used.

Permissions required match those from pg_tablespace_size.

In psql, include a new "Free" column in \db+ output.
