Not quite.
INSERT INTO base.neighborhood (column list)SELECT nextval('sequence name'), nameFROM base.clientsGROUP BY name;
Note that this will give you a different number for each of the
names. If what you want is for them all to have the same number,
then perform the nextval and then call currval() on the sequence.
By the way, this is a pretty common use of SQL (inserting into one
table the results of a select from another). If you thought this
wouldn't work, you maybe need a little more SQL practice than you
think you do. Any of the excellent PostgreSQL books out there should
cover this much. Alternatively, the standard SQL introductions would
get you there.
