No, there isn't. You could write one, though. For example, you could write:
(7.3 syntax)
CREATE FUNCTION yudie_format(text) RETURNS text AS
'SELECT SUBSTR($1, 1, 4) || ''-'' || SUBSTR($1,5,3) || ''-'' ||
SUBSTR($1,9,4);
' LANGUAGE SQL IMMUTABLE STRICT;
As a simple formatting function.
For that matter, it would be the work of a weekend for someone to write a
function in PL/Perl which would take a format mask and apply it to any text
string.
