[GENERAL] DB structure of PostGRE

Hi,my confession first..I have introduced myself this PostGRE db and I have a basic doubt?Where can I find a document about the structure of database/schema/users etc..and how is the data actually stored, like the datafiles, tablespaces. by now you must have guessed I have some knowledge of Oracle.
