FWIW I came up with a preliminary patch for a new psql command \dus that
shows settings. It takes a pattern that's used to constrain on roles.
Thus there is no way to view settings for a database. If there's a need
for that we could use another command, say \dls.

Sample output

alvherre=# \dus fo*
List of settings
role | database | settings
------+----------+-----------------------
fob | | log_duration=true
foo | alvherre | work_mem=256MB
: statement_timeout=10s
foo | | work_mem=512MB
: statement_timeout=1s
(3 rows)
