If you set it up with these settings then the disk space used is minimal: git_use_workdirs => 1, rm_worktrees => 1, So I have this on crake: andrew@emma:root $ du -sh REL*/pgsql 5.5M REL_10_STABLE/pgsql 5.6M REL_11_STABLE/pgsql 5.6M REL_12_STABLE/pgsql 5.6M REL_13_STABLE/pgsql 2.0M REL_14_STABLE/pgsql 2.6M REL9_5_STABLE/pgsql 5.5M REL9_6_STABLE/pgsql cheers andrew -- Andrew Dunstan EDB: https://www.enterprisedb.com
