CREATE OR REPLACE FUNCTION
FOOBAR(TEXT,TEXT)
RETURNS INT AS $$
SELECT(LENGTH($1) - LENGTH(REPLACE($1, $2, ''))) / LENGTH($2) ;
$$ LANGUAGE SQL IMMUTABLE;
SELECT FOOBAR('test test caa dtest testing EndofString', ' ');
foobar
--------
5
(1 row)
If there is not a system func for this, I will do this way.
Thank you for all inputs.
