Ludek,

Yup. Or it's a language problem. There's a fair Czech community of
PgSQL users, so hopefully you can get in touch with some of them. (Your
English is better than any of my 2nd languages -- it's just that
techincal docs are hard enough to understand in one's native language!)

Yes, it will. The query you want is:
SELECT * FROM table1 JOIN table2 ON (table1.id =
table2.table1_id)
LEFT OUTER JOIN table3 ON (table2.id = table3.table2_id);
