The defaults are store in pg_attrdef, the corresponding column definitions in pg_attribute.

So you would need to do a join between the two tables, something like:

select c.relname, a.attname, def.adsrc
from pg_attrdef def
   join pg_class c on def.adrelid = c.oid
   join pg_attribute a on a.attrelid = c.oid and a.attnum = def.adnum
where c.relname = 'the_table_name'
