2. Introduction — Introduction to PostGIS
WEBWhat is PostGIS?¶ PostGIS turns the PostgreSQL Database Management System into a spatial database by adding support for the three features: spatial types, spatial indexes, and spatial functions. Because it is built on PostgreSQL, PostGIS automatically inherits important “enterprise” features as well as open standards for implementation.
PostGIS 3.4.3dev Manual
WEBIntroduction. PostGIS is an extension to the PostgreSQL object-relational database system which allows GIS (Geographic Information Systems) objects to be stored in the database.

Chapter 5. Spatial Queries - PostGIS
WEB5.3.5. Create a new table with all the roads within the city of Prince George. This is an example of an "overlay", which takes in two tables and outputs a new table that consists of spatially clipped or cut resultants. Unlike the "spatial join" demonstrated above, this query creates new geometries.
Chapter 7. PostGIS Reference

As a result, most of the functions that you know and love have been renamed using the standard spatial type (ST) prefix. Previous functions are still available, though are not listed in this document where updated functions are equivalent.
