You might want to review several previous threads that were contemplating doing some reflink stuff with btrfs during database creation. Not exactly what you are doing, but related. Also, wouldn't it work if your extension just defined its own copydir() in the .so? That should then be used over the built-in one -- maybe. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
