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
