 # libsqlglot
 
 #### What this is
 
 sqlglot, in C++. 45 dialects, 126× faster on benchmark SQL, 252× on the kind your ORM generates when nobody's looking. Performance gap scales with query complexity, see [Benchmarks](#benchmarks). 
 
-Supports stored procedures (PL/pgSQL, T-SQL, MySQL, PL/SQL): where sqlglot falls back to passthrough, libsqlglot parses them into the AST.
-
 #### What it's for
 
 Anywhere SQL parsing meets the hot path: proxies, sidecars, migration, linters, Git pre-commit hooks, CI/CD pipelines. Also a replacement for every regex that's pretending to be a parser.
