The PostgreSQL documentation is quite good. I recommend looking
through it.

http://www.postgresql.org/docs/8.0/interactive/index.html

In particular, here:
http://www.postgresql.org/docs/8.0/interactive/sql-truncate.html

Google works pretty well also:

http://www.google.com/search?biw=892&hl=en&q=postgresql
+truncate&btnG=Google+Search

Hope this helps.

Something like this?

pg_dump --schema-only mydb > mydb.schema.dump
dropdb mydb
psql -f mydb.schema.dump mydb

You could use a query to generate the statements in psql:

\t
\o trunc_all.out

SELECT 'TRUNCATE ' || table_name || ';'
FROM information_schema.tables
WHERE table_schema='my_schema_name'
AND table_type='BASE TABLE';

\t
\o
