Call function with dynamic schema name

Hi to everyone,
I would like to use in my function (plpgsql or sql) dynamic schema name to
execute query or to call other functions.

For exemple in oracle is possible to excute query in this manner:


SELECT * FROM &&SCHEMA_NAME..TABLE_NAME;

Where I think &&SCHEMA_NAME. is a sessione variable.

I found tath I can use dynamic SQL like this:

execute 'select * from ' || schema_name || '.table_name';


However, I would like to know if exist any other system to use dynamic
schema name more similiar to Oracle. Another pl language is also ok.


Thank you very much.


Alessio
