Bug reference: 3673

PostgreSQL version: 8.2.5
Operating system: Fedora Core 5 / Red Hat Ent. Linux AS 3
Description: Untrusted perl language: ERROR: could not open relation
1663/16384/1259: No such file or directory
Details:

I have stored procedure in "plperlu" language. After the call to it Im
getting "could not open relation ... No such file or directory" on any next
operation in psql (the procedure itself works fine). If I'll close the
console and reopen it again, then everything works fine again (until the
next call to it).

Perl's SP code:

CREATE OR REPLACE FUNCTION fnc_prepare_base_dir (base_path IN TEXT)
RETURNS INTEGER AS
$$
my $base_path = $_[0];
my $status = 0;

if (-d "$base_path") {
chdir("$base_path");
@files = <*.cpio>;
foreach $file (sort @files) {
if (-f "$base_path/$file") {
$status = system("cd $base_path > /dev/null; cpio --quiet -idmv
--no-absolute-filenames < $file > /dev/null; rm -f $file > /dev/null");
if ($status > 0) {
return $status;
}
}
}
return 0;
}
else {
return 5;
}
$$
LANGUAGE plperlu;

To repeat this do the next:

$psql -U tham
