DUCKDB V2.0: YOUR DATABASE DESERVES A BETTER PARSER

Summary from the TLDR Data newsletter

DuckDB v2.0 replaces its PostgreSQL-derived SQL parser with a PEG-based parser while preserving the downstream binder and AST pipeline. The change removes Bison conflict pain, avoids exponential backtracking on malformed input, and enables runtime grammar extensions that can add syntax without reimplementing SQL parsing.
