AW: Error in pgAdmin4 when cast is created

Hi All,

 

I found this error in all versions of pgadmin4 on windows. When I create a cast like this:

 

CREATE FUNCTION public.text(smallint) RETURNS text STRICT IMMUTABLE LANGUAGE SQL AS 'SELECT textin(int2out($1));';

CREATE CAST (smallint AS text) WITH FUNCTION public.text(smallint) AS IMPLICIT;

 

Which I need for backward compatibility in our programm then I get the following error when I click on a some tables with the „SQL“ TAB open.

 

 

Error retrieving the information - INTERNAL SERVER ERROR

 

ERROR: operator is not unique: unknown || smallint

LINE 8: ELSE ARRAY['UNKNOWN OPTION' || i.indoption[i.attnum - 1]...

^

HINT: Could not choose a best candidate operator. You might need to add explicit type casts.

 

Here the complete statement from the pglog-file
