pg_put_line() Frustration

Hi all,

I am currently working on an application that will input multple lines into
a Postgre database. I am using the following code

$sql = "COPY table_2 FROM STDIN DELIMITER AS '\t'";
pg_query($dbc, $sql);
$sql = $data1."\t".$data2."\t".implode("\t",
$data)."\ttrue\t05-05-2005\n";
pg_put_line($this->dbc, $sql);
if(!pg_put_line($dbc, "\\N"))
{
pg_end_copy($dbc);
$error_message('Could not enter details');
}
else
{
pg_end_copy($this->dbc);
unset($data);
}

This gives me an example line like

57 BELF 254 0 10877 5138 0 0 true 05-05-2005

To go into a table with fields INT, CHAR(4) INT, INT, INT, INT, INT, INT,
BOOL, DATE

However, its not going in...

I'm getting an error

ERROR: missing data for column "col2"

With no data being inserted.

If anyone could point out where I'm going wrong I'd be forever in their debt

Thanks

Simon
