Thread: PgAdmin crash (1.10.0 beta4) + possible fix

PgAdmin crashes when browsing functions that only have a single out
parameters without a default value (BTW default values on out parameters
are not supported anyways)

The problem is in pgFunction.cpp(324).

To replicate the crash:
---------------------------------------------------------------------------
CREATE OR REPLACE FUNCTION out_test_crash_3(OUT integer)
  RETURNS integer AS
$BODY$
begin
$1 = 1000;
end;
$BODY$
  LANGUAGE 'plpgsql'
--------------------------------------------------------------------------

Then:
Refresh the function node in the tree and click on the function name above.

Possibe fix:
Included.

Thanks, applied with an additional fix to prevent an assertion in
dlgFunction::Go.
