AW: Error in pgAdmin4 when cast is created

Hi,

I tested the Statement and only a small correction is needed
SELECT
i.indexrelid,
CASE i.indoption[i.attnum - 1]
WHEN 0 THEN ARRAY['ASC', 'NULLS LAST']
WHEN 1 THEN ARRAY['DESC', 'NULLS FIRST']
WHEN 2 THEN ARRAY['ASC', 'NULLS FIRST']
WHEN 3 THEN ARRAY['DESC', 'NULLS ']
ELSE ARRAY['UNKNOWN OPTION' || (i.indoption[i.attnum - 1])::text, ''] <== Cast to text then it runs
END::text[] AS options,
i.attnum,
pg_get_indexdef(i.indexrelid, i.attnum, true) as attdef,
CASE WHEN (o.opcdefault = FALSE) THEN o.opcname ELSE null END AS opcname,
op.oprname AS oprname,
CASE WHEN length(nspc.nspname) > 0 AND length(coll.collname) > 0 THEN
concat(quote_ident(nspc.nspname), '.', quote_ident(coll.collname))
ELSE '' END AS collnspname
FROM (
SELECT
indexrelid, i.indoption, i.indclass,
unnest(ARRAY(SELECT generate_series(1, i.indnatts) AS n)) AS attnum
FROM
pg_index i
WHERE i.indexrelid = 1293689::OID
) i
LEFT JOIN pg_opclass o ON (o.oid = i.indclass[i.attnum - 1])
LEFT OUTER JOIN pg_constraint c ON (c.conindid = i.indexrelid)
LEFT OUTER JOIN pg_operator op ON (op.oid = c.conexclop[i.attnum])
LEFT JOIN pg_attribute a ON (a.attrelid = i.indexrelid AND a.attnum = i.attnum)
LEFT OUTER JOIN pg_collation coll ON a.attcollation=coll.oid
LEFT OUTER JOIN pg_namespace nspc ON coll.collnamespace=nspc.oid
ORDER BY i.attnum;

HI,

I inserted the Bug in the Bug-Tracker also with the correct SQL code, which comes, when I delete the cast

Hi,

Could you please report a bug on https://redmine.postgresql.org/projects/pgadmin4

It would be very helpful if you include the sample SQL definition to reproduce the issue on the developer's machine.

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
