Pavel,
CREATE OR REPLACE FUNCTION unnest(anyarray)
RETURNS SETOF anyelement as $$
SELECT $1[i] FROM generate_series(1,4) g(i)
$$ LANGUAGE sql;
pavel@postgres:5481=# select unnest(string_to_array('23,2,3,4,5',','));
unnest
--------
23
2
3
4
(4 rows)
Result is wrong: it must contain 5 rows.
How to make this work with with any array size ?
Some lines are long.
How to implement word wrap to new row in 80th position but between words
only ?
Andrus.
