I think your focusing on the wrong thing. Having a larger number for a PID does not cause problems. Please explain what problem your having.

EXAMPLES
Example #1
pg_lo_tell(3) example
<?php
$doc_oid = 189762345;
$database = pg_connect("dbname=jacarta");
pg_query($database, "begin");
$handle = pg_lo_open($database, $doc_oid, "r");
// Skip first 50000 bytes
pg_lo_seek($handle, 50000, PGSQL_SEEK_SET);
// See how far we've skipped
$offset = pg_lo_tell($handle);
echo "Seek position is: $offset";
pg_query($database, "commit");
?>
The above example will output:
Seek position is: 50000
