pg_put_line() and file()

[wxdqz]

Hi.
I was tinkering around with pg_put_line and pg_end_copy and rather than inserting data from a variable as per the example, I was wondering if it was posible to insert the data from a delimited file via these two functions.
I produced a dump from postgres and tried inserting the data raw
$text = file("test.sql");
$db = pg_connect("host=localhost dbname=testing user=testing");
pg_exec($db, "COPY test FROM stdin");
foreach($text as $line) {
echo $line, "<BR>";
pg_put_line($db,$line);
flush();
}
pg_end_copy($db);

but this caused an error to occur. The example in the docs had the new lines and tabs escaped so I tried that as well with addslashes()

$text = file("test.sql");
$db = pg_connect("host=localhost dbname=graeme user=graeme");
pg_exec($db, "COPY test FROM stdin");
foreach($text as $line) {
$line = addslashes($line);
$line = ereg_replace(9,"\\t",$line);
$line = ereg_replace(10,"\\n",$line);
echo $line, "<BR>";
pg_put_line($db,$line);
flush();
}
pg_end_copy($db);

and while the data was exactly the same format as the example, I managed to get postgres stuck in COPY and had to manually kill the postgres COPY process to recover.
Any one have any ideas?

Cheers,
Graeme
