Does anything dump per-database config settings? (was Re: ALTER DATABASE vs pg_dump)

Actually, I'm not sure pg_dumpall does them either.

tracker=> SELECT name,setting,source FROM pg_settings WHERE name = 
'DateStyle';   name    | setting  |  source
-----------+----------+---------- DateStyle | SQL, DMY | database
(1 row)

pg_dumpall -U postgres -p 5483 -g > tracker.global.schema
pg_dump -U postgres -p 5483 --schema-only > tracker.schema
grep -i datestyle tracker*schema
<nothing>

That's with 8.3.3

Am I doing something stupid here?
