Can we see the code that created that ?

[raderio]

Well, it's liquibase migration. So, I don't have code.

@raderio , can you provide more details?
Is the issue reproducible every time?

ArrayIndexOutOfBoundsException: null looks like a JIT compiler bug

In the mean time, this passes for me with Oracle jdk1.8.0_102

public class StatementTest ... {
...
  public void testPlpgsql() throws SQLException {
    String str = "CREATE OR REPLACE FUNCTION update_on_change() RETURNS TRIGGER AS $$\n"
        + "BEGIN\n"
        + "NEW.updated_at = NOW();\n"
        + "RETURN NEW;\n"
        + "END;\n"
        + "$$ language 'plpgsql';";

    PreparedStatement ps = null;
    try {
      ps = con.prepareStatement(str);
      System.out.println("ps.executeUpdate() = " + ps.executeUpdate());
    } finally {
      TestUtil.closeQuietly(ps);
    }
  }

as does this for me:

Connection con =
DriverManager.getConnection("jdbc:postgresql://localhost/test",
"test", "");
con.createStatement().execute("CREATE OR REPLACE FUNCTION
update_on_change() RETURNS TRIGGER AS $$\n" +
"BEGIN\n" +
"NEW.updated_at = NOW();\n" +
"RETURN NEW;\n" +
"END;\n" +
"$$ language 'plpgsql';\n" +
"\n");

con.prepareStatement("CREATE OR REPLACE FUNCTION update_on_change()
RETURNS TRIGGER AS $$\n" +
"BEGIN\n" +
"NEW.updated_at = NOW();\n" +
"RETURN NEW;\n" +
"END;\n" +
"$$ language 'plpgsql';\n" +
"\n").execute();

Thank you. I think It's liquibase bug.

"Unterminated dollar quote" leads to ArrayIndexOutOfBoundsException.
I think it makes sense to have proper error messages for that at pgjdbc level.

  public void testPlpgsql() throws SQLException {
    String str = "CREATE OR REPLACE FUNCTION update_on_change() RETURNS TRIGGER AS $$\n"
        + "BEGIN\n"
        + "NEW.updated_at = NOW();\n"
        + "RETURN NEW;\n"
        + "END;";

    PreparedStatement ps = null;
    try {
      ps = con.prepareStatement(str);
      System.out.println("ps.executeUpdate() = " + ps.executeUpdate());
    } finally {
      TestUtil.closeQuietly(ps);
    }
  }
