Chapter 7. Server-Side Programming with PL/pgSQL

The ability to write functions in PostgreSQL is an amazing feature. One can perform any task within the scope of the database server. These tasks might be related directly to data manipulation such as data aggregation and auditing, or can be used to perform miscellaneous services such as statistics collection, monitoring, system information acquisition, and job scheduling.

In this chapter, our focus is the PL/pgSQL language. PL/pgSQL can be considered as the default PostgreSQL, which is a full-fledged procedural language. As mentioned earlier in Chapter 4, PostgreSQL Advanced Building Blocks, PL/pgSQL is installed by default in PostgreSQL.

Modern Computer Vision with PyTorch

Modern Computer Vision with PyTorch

This book provides a hands-on approach to solving over 30 prominent real-world computer vision problems using PyTorch 2.x on actual datasets. Here you'll learn to build a neural network from scratch and optimize hyperparameters, perform image classification, multi-object detection, segmentation, and more. You'll also explore facial expression manipulation and combining CV with NLP and RL techniques, build generative AI applications, and take your model to production on AWS. By the end of this book, you'll master modern NN architectures and confidently solve real-world CV problems.
