PostgresSQL 9.2 Installation

Hi Team,

I have installed "PostgreSQL 9.2 in my local machine". And I am trying to execute the below statement.

statement:
"DECLARE v_num number".

And I am getting the below error:
type "number" does not exist.
And its not supporting any oracle data types functions.As I knew "PostgressSQL9.2" supports pl/sql data types and functions.
Kindly suggest what can be the issue and how to go about it
