New UUID versions

Primary key generation is a known issue quite efficiently though not ideally solved by sequences. There are still problems with distributed generation, real uniqueness and predictability. Initially, UUID was not intended for use as a DBMS key, but its new versions (6, 7 and 8) make it quite convenient to use them as both synthetic and natural keys.

Review of some historical CVEs

I'm not a real security expert. But this will help me to do ELI5 explanation of the funniest historical Postgres CVEs.

Oracle-like packages in Postgres Pro Enterprise 15

One of the main problems when migrating from Oracle to PostgreSQL is PL/SQL packages.

The PostgreSQL DBMS lacks such functionality - this leads to the need to rewrite (up to its redesign!) the Oracle PL/SQL code to PL/pgSQL.

With the new version of its flagship Postgres Pro 15 Enterpise distribution, Postgres Pro has added support for package functionality: the PL/pgSQL syntax has been extended and new mechanisms have been added to the stored procedure runtime environment. The report will focus on supporting the functionality of packages in Postgres Pro 15 Enterpise: - grouping types of variable procedures and functions into a package; - support for the package initialization section; - support for global package variables available throughout the "life" of the session.

This presentation will also discuss the features of migration of packages from Oracle to Postgres Pro Enterprise DBMS.
