Oracle to PostgreSQL

Hi,

I have almost 1300 files from Oracle (no access to oracle server).  I
have to create the tables and data as follows.

-- start script

-- file name:  aa_asset_type.sql

CREATE TABLE AS_ASSET_TYPE
(
  MAIN_TYPE         CHAR(3)                     NOT NULL,
  SUB_TYPE          NUMBER(3)                   NOT NULL,
  DESCRIPTION       VARCHAR2(25)                DEFAULT ' '
       NOT NULL,
  SERVICE_SCHEDULE  VARCHAR2(8)                 DEFAULT ' '
       NOT NULL,
  PRODUCT_CODE      CHAR(4)                     DEFAULT ' '
       NOT NULL
);

GRANT ALTER, DELETE, INDEX, INSERT, REFERENCES, SELECT, UPDATE ON
GENADMIN.AS_ASSET_TYPE TO PUBLIC;

INSERT INTO AS_ASSET_TYPE ( MAIN_TYPE, SUB_TYPE, DESCRIPTION, SERVICE_SCHEDULE,
PRODUCT_CODE ) VALUES (
'000', 0, ' ', ' ', '    ');
INSERT INTO AS_ASSET_TYPE ( MAIN_TYPE, SUB_TYPE, DESCRIPTION, SERVICE_SCHEDULE,
PRODUCT_CODE ) VALUES (
'001', 0, ' ', ' ', '    ');
INSERT INTO AS_ASSET_TYPE ( MAIN_TYPE, SUB_TYPE, DESCRIPTION, SERVICE_SCHEDULE,
PRODUCT_CODE ) VALUES (
'100', 0, 'BUILDINGS', ' ', '    ');

Unfortunately When I execute the above files using \i I am getting errors like

ERROR:  syntax error at or near "("
LINE 4:   SUB_TYPE          NUMBER(3)                   NOT NULL,

Obviously 'number' is not PostgreSQL data type so is 'varchar2'.  What
is your suggestion to create these tables in PostgreSQL?  Should I
pre-process using Sed/Awk to find/replace the field type first?  Any
recommendation is greatly appreciated :)

Thanks.
