There are several ways to do it, depending on what you want.
You can create a new table (with no constraints):
SELECT * INTO new_table FROM old_table;
Or create the new table with any necessary constraints, then:
INSERT INTO new_table SELECT * FROM old_table;
Or dump to text and edit the dump file to change all occurrences of the
table name:
pg_dump -d my_database -t old_table > dump.sql
vi dump.sql
psql -d my_database < dump.sql
or edit on the fly (if the old table name doesn't occur except as a
table name):
pg_dump -d my_database -t old_table |
sed -e 's/old_table/new_table/g' |
psql -d my_database
