Question

I am facing an issue when I'm trying to create a PROCEDURE using EmbeddedPostgres

Rest everything is working except for when I'm trying to create a PROCEDURE Please find below the code.

EmbeddedPostgres pg = EmbeddedPostgres.builder().start();
Statement dbSetup = pg.getDatabase("postgres", "postgres").getConnection().createStatement();
dbSetup.execute("create database portal;");
dbSetup.execute("CREATE USER testadmin WITH PASSWORD 'testadmin123' CREATEDB;");
dbSetup.execute("ALTER USER testadmin WITH SUPERUSER;");
dbSetup.execute("ALTER ROLE testadmin SUPERUSER;");

String procedure = "CREATE PROCEDURE insert_data(a integer, b integer)\n" +
                   "LANGUAGE SQL\n" +
                   "AS $$\n" +
                  "INSERT INTO tbl VALUES (a);\n" +
                  "INSERT INTO tbl VALUES (b);\n" +
                  "$$;";

ResultSet rsnew = pg.getDatabase("testadmin", "portal").getConnection().createStatement().executeQuery(procedure);

Facing the below Exception
