I don't know how JDBC does it, but as an example the Perl Pg module has
these functions:
$ret = $conn->putline($string)
Sends a string to the backend. The application must explicitly
send the two characters "\." to indicate to the backend that it
has finished sending its data.
$ret = $conn->putnbytes($buffer, $nbytes)
Sends n bytes to the backend. Returns 0 if OK, EOF if not.
$ret = $conn->endcopy
This function waits until the backend has finished the copy.
It should either be issued when the last string has been sent to
the backend using putline or when the last string has been
received from the backend using getline. endcopy returns 0 on
success, 1 on failure.
Looking at google I see the following:
http://archives.postgresql.org/pgsql-jdbc/2004-10/msg00166.php
saying it's not supported but there is a patch. That was a year ago
though. Some later emails suggest it is possible.
Hope this helps,
