In this video, we explored the source code to comprehend how PostgreSQL handles SQL queries from clients and processes them into a parse tree. The lexer file defines tokens like space, database, etc., while the grammar file establishes rules for query execution. The abstract syntax tree is generated to execute queries. Open Source tools like Flex and Bison are used to generate C code for lexer and grammar files. The build process compiles these files into the PostgreSQL binary for server management.
