Oh it is called "INSERT INTO", thank you!
I still have a problem though:
# select uid, name, mail, created, access from drupal_users;
uid | name | mail | created | access
-----+------+----------------------------+------------+------------
0 | | | 0 | 0

# INSERT INTO drupal_users (uid, name, mail, created, access)
SELECT user_id, username, user_email, user_regdate, user_lastvisit
FROM phpbb_users
WHERE user_id > 50 and length(username) > 0;
ERROR: duplicate key value violates unique constraint "drupal_users_name_key"
I don't understand, what is wrong with "name" here and
how to find the troublemaking record in my 4700 lines table
# \d+ drupal_users_name_key;
Index "public.drupal_users_name_key"
Column | Type | Storage | Description
--------+-----------------------+----------+-------------
name | character varying(60) | extended |
unique, btree, for table "public.drupal_users"
Using PostgreSQL 8.4.7
Thank you
