/>Testcase:(8.4 CVS head)<br />====================<br />   CREATE OR REPLACE FUNCTION f007( a INTEGER, <br
/>           b INTEGER DEFAULT 10 ) RETURNS INTEGER <br />   AS $$ <br />       select 10; <br />   $$ language sql;
<br/><br />   CREATE OR REPLACE FUNCTION f007( a INTEGER DEFAULT 10, <br />            b INTEGER DEFAULT 10, <br
/>           c INTEGER DEFAULT 10) RETURNS INTEGER <br />   AS $$ <br />       select 10; <br />   $$ language sql; <br
/><br/>   CREATE OR REPLACE FUNCTION f007( a TIMESTAMP DEFAULT to_date('01-JUN-06 14:03:50', 'DD-MON-YY HH24:MI:SS') )
RETURNSTIMESTAMP <br />   AS $$ <br />       select current_date::timestamp; <br />   $$ language sql; <br /><br
/>postgres=#SELECT f007( to_date('01-JUN-06 14:03:50', 'DD-MON-YY HH24:MI:SS') ); <br />ERROR:  functions with
parameterdefaults f007(integer, integer, integer) and f007(integer, integer) are ambiguous <br /><br /><br />I think
thisshould not return error as the input args here is timestamp... inputs?<br /><br />Thanks,<br />Rushabh Lathia<br
