    Hardening is the process of strengthening the security of a system in order to reduce risks from possible threats. In my presentation, I will tell you how to protect service cluster communications using TLS connections, in order to avoid accidental or unauthorized access to Patroni's REST API and ETCD storage.

    Postgres Pro is investing heavily to make it easy for customers to migrate to their database from Oracle Database.

    This talk describes in detail the advanced Postgres Pro DBMS technologies designed to solve this problem:

    • support for package functionality in PL/pgSQL, including the package initialization section and global package variables;
    • ora2pgrpo utility for automatic conversion of package code from Oracle PL/SQL syntax to PL/pgSQL;
    • PG Pro Application Info extension designed for instrumentation and monitoring of the state of sessions, including the execution of long operations (session longops) - a functional analogue of the package DBMS_APPLICATION_INFO in Oracle DBMS;
    • new system packages UTL_MAIL and UTL_SMTP for sending emails from stored procedures to Postgres Pro DBMS (full functional analogue of the corresponding packages in Oracle DBMS);
    • new system package UTL_HTTP for interacting with external sources from stored procedures in Postgres Pro DBMS (analogous to the package of the same name in Oracle DBMS);

    Also in this talk there will be a short story about the directions of development of the Postgres Pro DBMS aimed at further simplifying migration from Oracle DBMS.

    Facing the restrictions on the use of Western software, our bank has developed and put into commercial operation a reliable mechanism for data replication between two DBMSs. This mechanism allowed the bank's teams without any special restrictions to replace the product from Oracle (Oracle Golden Gate was previously used in the bank for a long time). In the presentation, we will talk about the main advantages of our software and the nuances of its use.
