"oracle to postgresql" conversion - Mailing list pgsql-general

I'm a newbie in Oracle and postgreSQL,
i'm need to translate the following script (in Oracle) to postgreSQL :


rem Autorisation des lignes vides :
set sqlbl on

rem Initialisation du timer :
set timing on

rem Creation de la table :

CREATE TABLE "LEPAPE"."EXPERIENCE"(
    "EXP_ID" VARCHAR2(16) NOT NULL,
    "MEASURE" VARCHAR2(10) NOT NULL,
    "THRESHOLD" NUMBER NOT NULL,
    "NB_NODES" NUMBER(3) NOT NULL,
    "TOTAL_TIME" VARCHAR2(10) NOT NULL,
    "SC_ID" NUMBER(6) NOT NULL,
    "GRANULARITY" VARCHAR2(10) NOT NULL,

    CONSTRAINT "SYS_C009967" CHECK(measure in ('age', 'num','order')))



Thanks!
