Using PostgreSQL in AWS RDS: problems, recipes and tools.

Everyone has probably heard about such a service as AWS RDS. I will talk about my experience by using the AWS RDS PostgreSQL Engine: the positive and negative aspects of the DBA work. This talk will focus on the tools that helped me create a comfortable environment in RDS. https://www.dropbox.com/s/v7udx5x96as5gbd/pgconf2020.pdf

Writing a User-defined datatype

Walk-through of extending PostgreSQL with a user-defined type. The journey begins from the basics, from creating simple domain types over existing types, and continues to implementing a full-blown datatype from scratch in C.

PostgreSQL's advanced index types, GiST, GIN, and SP-GiST, are covered in enough detail to give an understanding of what each of them is good for. Support functions for each of them are shown for the example 'color' datatype.

Fault-tolerance cluster PostgreSQL + Patroni

I will speak about our experience in solving the fault-tolerance problem for PostgreSQL, which options we reviewed and how we chose Patroni.

I will cover solution testing, quick implementation to the production and issues we faced as well as the way we solved them.

PostgreSQL configuration master class for 1C

You will have a fascinating journey through PostgreSQL settings. We will talk about that with 1C not so or on the contrary so that under it it is necessary to adjust specially DBMS. We will discuss approaches to testing the speed of 1C. Consider the various options for backup schemes and fault tolerance. In the process, we will compare the speed of 1C on PostgreSQL configured by default with the speed of 1C configured for PostgreSQL. Also, we will create a replica of PostgreSQL, and switch to it the 1C Server "live", see what users will see 1C during this operation. And a separate block will be devoted to Postgres Pro Enterprise Edition, how the use of its advantages affects the speed of 1C.
