PGConf.SPB 2023

I have been working with 1C on PostgreSQL for 6 years, and the DBMS has changed significantly since I started. In this presentation, I'm going to cover the progress it has made. The users will, just as always, claim that this is not enough. So in addition to milestones and achievements, I'll tackle the possible feature requests from the maintenance viewpoint and explain some workarounds.

An important aspect of PostgreSQL database security and reliability is backup practices. The talk will reveal the main techniques and methods used to protect data, prevent loss and successfully recover information in case of human error, failures or emergencies. We will tell how CyberBackup helps to protect PostgreSQL, including configuration in Patroni cluster: we will consider system deployment options, important aspects of backup policy configuration, including full and incremental backups. We will also show how to easily work with backups via mount and do granular restores.

We'll talk about the tool we created, which monitors changes in the database and creates scripts for migrations of selected objects both interactively and automatically.

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.
