There is a database template1 you can play with.
If there is no table in template1, you can create one by:
psql template1
psql> create table mytable (
psql> mydate datetime,
psql> mymem text);
psql> insert into mytable values('now', 'I am doing this today');
psql> select * from mytable;
psql>\q;
dump your database:
pg_dump template1 > mydump.pgdump
create another copy of this database:
createdb newdatabase
cat mydump.pgdump | psql newdatabase
have a look at your new database
psql newdatabase
psql>\d;
psql>select * from mytable;
(add a new column)
psql>alter table mytable add column priority text;
psql>insert into mytable values('now', 'Always play at first, then ...',
'super high');
psql>select * from mytable;
psql>\q;
Have a lot of fun!
