[patch] add COPY functions to pdo_pgsql

What do these do? I.e. where's the documentation or RFC http://wiki.php.net/rfc ? :)

So the patch can be found easily, can you update the bug with a link to it?

I updated the bug with a link to the list archives.

I'm not familiar with http://wiki.php.net/rfc. README.SUBMITTING_PATCH
didn't mention anything about it, or really anything about
documentation. Should I just tell you, or is there something special I
should do? Most of the things on the rfc look like much bigger changes
than this.

Apparently Ilia Alshanetsky's the maintaining, so I'm CCing them. The
version I started working on said unknown, and I didn't think to check
again when I switch to subversion.

Those functions are basically php wrappers around the 3 similarly named
functions found on http://www.postgresql.org/docs/8.1/static/libpq-copy.html

You issue a COPY TO STDOUT query and then run pgsqlGetCopyData until it
returns false.
Or you issue a COPY TO STDIN query and calld pgsqlPutCopyData repeatedly
to send your data, then pgsqlPutCopyEnd when you're done.

Example php code:
$db = new PDO($dsn, $user, $pass, $driver_options);
$db->query("COPY users TO STDIN WITH CSV");
while (($ret = $db->pgsqlGetCopyData()) !== false)
echo "x: $ret\n";

$db->query("COPY test FROM STDIN WITH CSV");
$db->pgsqlPutCopyData("1,blah\n");
$db->pgsqlPutCopyData("2,asdf\n");
$db->pgsqlPutCopyEnd();
