I use this little perl function:
sub runscript($)
{
my $fname = pop;
open(F, $fname) or die;
print "executing $fname\n";
my $sql = <F>;
$db->do($sql) or die 'cant start copy';
my $c = 0;
while (<F>)
{
$db->pg_putline($_);
if ($c % 10_000 == 0) {
print "$c\r";
if ($stop) { die; }
}
$c++;
}
print "$c total\n";
$db->pg_endcopy;
unlink($fname);
}
The first line in the file needs to be the sql copy command, like:
print F "copy junk(id, name, address) from stdin;\n";
The following lines are the data, like:
print F "$id\t$name\t$add\n";
