In Hibernate using update but still going for a create table

Question

Using Hibernate in my project. I am getting create table queries at my logs,

But I am using a HBM2DDL_AUTO="update"

What else could had been missed?

PS: I get these logs only when the tables are already present at runtime. If tables not present, it obviously runs smooth.

Here are the properties

Properties settings = new Properties();
settings.put(Environment.DRIVER, "org.postgresql.Driver");
settings.put(Environment.URL, "jdbc:postgresql://" + jdbc_host + ":5432/" + jdbc_database + "?prepareThreshold=0");
settings.put(Environment.USER, jdbc_user);
settings.put(Environment.PASS, jdbc_password);
settings.put(Environment.DIALECT, "org.hibernate.dialect.PostgreSQLDialect");
settings.put(Environment.SHOW_SQL, "true");
settings.put(Environment.CURRENT_SESSION_CONTEXT_CLASS, "thread");
settings.put(Environment.HBM2DDL_AUTO, "update");

Error Logs:

I have not worked postgresql in java but I've worked with MySQL. And Whenever' I need to create the table using hibernate then I mention the follow feature in application.properties and it allow to create the table. please once go for it and if it still doesn't work please inform me. Put it in proprerties.

spring.jpa.hibernate.ddl-auto=update
