Re: bytea size limit?

Here's the full code sample for a minimalistic reproduction of the
error. When you run it, if you increase the size (through the command
line argument, you get an out of memory error. On my machine, after
the size gets higher than about 1400000 bytes. I can make it happen every
time.

The DB table has two fields:

id: integer
data: bytea

import java.sql.*;
import java.io.*;
import java.util.*;

public class BlobTest {
public static void main(String[] args) {
Connection c = null;
try {
Class.forName("org.postgresql.Driver");
String url = "jdbc:postgresql://myserver/mydb";
c = DriverManager.getConnection(url, "myuser",
"mypass");

String sql = "INSERT INTO blobtest (id, data)
VALUES(?,?)";

int size = Integer.parseInt(args[0]);

byte[] data = new byte[size];

int id = Math.abs(new Random().nextInt());

PreparedStatement stmt = c.prepareStatement(sql);
stmt.setInt(1, id);
stmt.setBinaryStream(2, new ByteArrayInputStream(data), data.length);

stmt.executeUpdate();

stmt.close();
}
catch(Throwable t) {
t.printStackTrace();
}
finally {
try { c.close(); } catch(Exception e) {}
}
}
}
