Re: plperl "set-valued function" problem

Thanks Alvaro

I checked out the files from: pgsql/src/pl/plperl/sql/ and
pgsql/src/pl/plperl/expected and compared the results

I still found a difference in 2 functions :
====================
Function 1 - Expected:
====================
CREATE OR REPLACE FUNCTION perl_spi_prepared(INTEGER) RETURNS INTEGER AS $$
my $x = spi_prepare('select $1 AS a', 'INTEGER');
my $q = spi_exec_prepared( $x, $_[0] + 1);
spi_freeplan($x);
return $q->{rows}->[0]->{a};
$$ LANGUAGE plperl;

SELECT * from perl_spi_prepared(42);

perl_spi_prepared
-------------------
43
(1 row)

====================
Function 1 - Actual Output:
====================
ERROR: error from Perl function: type "integer" does not exist at line 2.

====================
Function 2 - Expected:
====================
CREATE OR REPLACE FUNCTION perl_spi_prepared_double(double precision)
RETURNS double precision AS $$
my $x = spi_prepare('SELECT 10.0 * $1 AS a', 'DOUBLE PRECISION');
my $q = spi_query_prepared($x,$_[0]);
my $result;
while (defined (my $y = spi_fetchrow($q))) {
$result = $y->{a};
}
spi_freeplan($x);
return $result;
$$ LANGUAGE plperl;

SELECT perl_spi_prepared_double(4.35) as "double precision";

double precision
------------------
43.5
(1 row)

====================
Function 2 - Actual Output:
====================
ERROR: error from Perl function: invalid name syntax at line 2.

Is this due to a bug? I think this is related - a problem with typename aliases

http://archives.postgresql.org/pgsql-bugs/2007-01/msg00111.php

Even if this is a bug and it has been logged, how did the author of
these files generate the result sets as seen in the .expected files?
Has he been using a newer version of Postgres?

I am using the PG 8.2.3 WinXP installer downloaded on 07 Feb 2007

Thanks

Sami
