Ezequias-

first you will need to pg_dump everything.. schema..tables..functions then your 
Data into a text format which has no whitespace characters
There are 2 bulk loaders available from Oracle
1)Brand new DataPump
2)Tried and true sqlldr (which I recommend)
I would highly recommend reading and understanding the Extract / Transform 
/Load document located at
http://www.oracle.com/technology/obe/obe10gdb/bidw/etl2/etl2.htm
Also triple check the extents you are allocating for the tablespace for tables 
to be inserted into that tablespace will guaranteed to be sufficient size
(If you dont know the size of a block ask..as this isnt something you can fix 
later..unless you want to spend a 3day weekend doing a rollback..)
Become familiar with LOAD DATA INFILE command links available from either 
Stanford (or Oracle)
http://infolab.stanford.edu/~ullman/fcdb/oracle/or-load.html
Be mindful that Oracle DB is used by ALL of the major players
so inserting nulls which could violate any constraint (constraints being unique 
or foreign key) are forbidden
In fact inserting nulls into any column is discouraged as it may violate the 
relationship of dependent table records to primary table
If you have time and or diskspace constraint you may want to look at Direct 
Path Loading which creates preformatted data blocks
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96524/c21dlins.htm
Caveat emptor with this option as the logger is turned off and if there are any 
burps along the way you wont know which record it burped on

Feel free to ping me if you have any questions/

Saludos Cordiales,

  33 tables
  8 functions

  Has someone any idea ?
