Indeed, all \d* which display perms have the empty/default confusion:
\dp \ddp \des \dew \l \dn \db \df \dT \dD \dL
I fixed them all to display the default acl in the patch I just sent.
I also noticed that although large objects have permissions, they are not printed by any backslash commands.
Also using \df to display permissions is inconvenient because \df+ is required, which also shows function source code which usually overwhelms the rest of the display. Any chance we can remove the source code column from \df now that we have \sf? I usually avoid looking at function permissions and select directly from pg_proc if I absolutely must know.
