some questions : psql

hi,

i have some questions about psql.
i'm trying to write a script for deploying my database and i have some questions :
1- is it possible to set a default schema ?
i tried : set DEFAULT SCHEMA base1; but it didn't worked

2- is it possible to have one file with global values and to use them when creating functions.
one example is : i have a temporary directory, and several functions need to access this folder, so is it possible to pass the path as with Oracle
DEFINE TempDirectory = /home/....
@createMDNS.sql &TempDirectory


3- my psql script create 2 tablespaces, an user, the database, 1 schema and the tables and functions
but when i launch pgadmin, i see my new user, the tablespace and the database, but I don't see the schema and in consequence the tables and functions.
but all have been created because i can ask tables, but they don't appear and i don't know why...;

thank a lot
regards

Will
