Use pg_dump with the -s switch to get just the schema and objects but no data out. pg_dump --help will give you a list of all the options that command has. To put your new schema into another database, just redirect that file to psql:
pg_dump -s -h olddbserver olddbname > schemafile.sql psql -h newserver newdbname < svhemafile.sql 2: pg_dump is the best way to go. pg_dumpall can dump everything, including user accounts from one server. Then feed the output to psql or pg_restore. 3: pg_dump is export, psql or pg_restore are import
