Forum OpenACS Q&A: Response to Postgres Backups: pg_dump -D still necessary?

I've always done the dump in 7.1.2 with pg_dump without flags, and have worked fine, then when I want to reload,
after creating the database,

I createlang plpgsql, pltcl

and do psql -f /web/yourservice/www/doc/sql/postgres.sql yourservice

and psql -f yourdump yourservice
