Expected behavior

I have to plpgsql functions with the same name but different argument list. (Yes, this is possible in postgresql.) In the left panel, under the Functions group, I can see both. However, the content of the CREATE Code panel shows the same content, regardless of which of them I click on the left panel.

Current behavior

Only one of the functions' CREATE code is readable, I cannot see the other one.

Failure information (for bugs)

This is a bug. The following query returns two records but only the function body belonging to the first one is shown:

SELECT "p"."prosrc", "p"."proargnames", "p"."proargtypes", "p"."prorettype"
FROM "pg_catalog"."pg_namespace" AS "n"
JOIN "pg_catalog"."pg_proc" AS "p" ON "p"."pronamespace" = "n"."oid"
WHERE "n"."nspname"=E'public'AND "p"."proname"=E'summa';

Steps to reproduce

Please provide detailed steps for reproducing the issue.

  1. create two functions with identical name and different argument list:
CREATE FUNCTION summa(integer, integer) RETURNS integer LANGUAGE plpgsql AS 
	_ret INTEGER;
   SELECT $1 + $2 INTO _ret;
   RETURN _ret;

CREATE FUNCTION summa(integer, integer, integer) RETURNS integer LANGUAGE plpgsql AS 
	_ret INTEGER;
   SELECT $1 + $2 + $3 INTO _ret;
   RETURN _ret;
  1. Open the Functions branch of the left-hend-side tree

  2. click each of the names once

  3. You will see that the body of the displayed function is always the first one and you cannot see the body of the second one.


Please provide any relevant information about your setup. This is important in case the issue is not reproducible except for under certain conditions.

The next build should fix that. Internally, the argument types list is used to distinct between multiple procedures. E.g. your example procedures have "23 23" and the other one has "23 23 23". Taking that into account when selecting the routine body, we get only one procedure, not two.
