In the previous post , we explored how the compiler transforms IR into SSA—a representation where every variable is assigned exactly once. We saw how the compiler builds SSA using Values and Blocks, …

In the previous article , we explored how PostgreSQL’s planner chooses the optimal execution strategy. The planner produces an abstract plan tree—nodes like “Sequential Scan,” …

In the previous post , we explored the IR—the compiler’s working format where devirtualization, inlining, and escape analysis happen. The IR optimizes your code at a high level, making smart …

In the previous article , we explored how PostgreSQL’s rewriter transforms queries—expanding views, applying security policies, and executing custom rules. By the end of that phase, your query …

In the previous posts , we’ve explored how the Go compiler processes your code: the scanner breaks it into tokens, the parser builds an Abstract Syntax Tree, the type checker validates …

In the previous article , we explored how PostgreSQL transforms SQL text into a validated Query tree through parsing and semantic analysis. By the end of that journey, PostgreSQL knows that your …

In the previous post , we explored how the Go compiler’s type checker analyzes your code. We saw how it resolves identifiers, checks type compatibility, and ensures your program is semantically …

In the previous article , we explored how PostgreSQL establishes connections and communicates using its wire protocol. Once your connection is established and the backend process is ready, you can …

In the previous posts , we explored the scanner—which converts source code into tokens—and the parser —which takes those tokens and builds an Abstract Syntax Tree.

In future posts, I’ll cover …

In the previous article , we explored the complete journey a SQL query takes through PostgreSQL—from parsing to execution. But before any of that can happen, your application needs to establish a …
