Yes, you might use the perl DBI module. This supports pg. Then
you can code like this:

my $conn;
my $dbname = 'foo'; # Your database's name.
my $tablename = 'foobar';
$conn = DBI->("dbi:Pg:dbname=$dbname", $pguser, '', {} );
# your SQL-stuff, like:
$conn->do("INSERT INTO $tablename (column1) values ('$data')");
$conn->disconnect;

Just to give you an idea. :-)

What means error 32515?

Let me site some text from the perlfunc man page

system LIST
Does exactly the same thing as "exec LIST" except
that a fork is done first, and the parent process
waits for the child process to complete. Note
that argument processing varies depending on the
number of arguments. The return value is the exit
status of the program as returned by the wait()
call. To get the actual exit value divide by 256.
...

Ok, dividing 32512 by 256 gives me 127.

127 is the exec's (and bash's too) return code if the command
could not be found.

Cron jobs start with a reduced environment. Maybe something
important is missing, at least a search path and psql isn't
found. Try to use an absolute path. Try to run this command as
batch job, don't throw it's output away and look the resulting
e-mail message.

Good Luck!
