Script load order and description:

1) Load schema.sql
    Creates all tables

2) Load tsearch.sql
    Configures full text indexing

3) Load functions.sql
    Creates PL/pgsql functions

4) Load data.sql
    Loads sites, exclusions and lists. It's either this or restore a backup
    of those tables.

-> recommended to perform initial indexing here, for performance reasons

5) indexes.sql
    Create fulltext indexes and date index
