To save some work, here is the fix for schema browser:
In sb_get_table_description
select
conname as constraint_name,
consrc as constraint_source
from
pg_constraint r join (select oid from pg_class where relname = lower(:table_name)) c
on (c.oid = r.conrelid)
order by constraint_name
The problem is the changed system catalog names, but this should fix your problem. I don't know when I will have time to patch the proc, it needs an if for pg_version.
