Creating schema for multiple tables/fields/indices.

I just downloaded postgreSQL.  I have finished the install and everything
looks okay.  I am now ready to create a db and add tables/fields/indices.  I
have approx. 100 tables 2,000 fields and 500 indices.  Before I spend an
ungodly amount of time doing these individually, can I load an entire schema
via some scripting method?
