+## Recent Parser Improvements and Benchmark Snapshot
+
+This repository has recently added tolerance and compatibility fixes across
+multiple dialects, including:
+
+- ClickHouse: richer dotted/typed access parsing (`expr.:Type`, `expr.^field`, `.null` field paths), plus broader support for alias-heavy query forms.
+- DuckDB: alias-first projection support (`alias: expr`) and DESCRIBE-in-subquery tolerance.
+- PostgreSQL: `BIT VARYING(n)` cast tolerance, JSON key/value argument parsing (`'k' : v`), richer `ON CONFLICT (...)` target parsing, and broader geometric/operator-sequence tolerance.
+- MySQL: improved UPDATE/DELETE tolerance around ORDER BY, LIMIT, PARTITION, and insert alias edge cases.
+- T-SQL / ANSI extensions: tolerance for `WITH XMLNAMESPACES (...)` and additional parser guardrails for mixed corpora.
+
+Benchmark reference:

+- [SQL AST Benchmark](https://sql-ast-benchmark.luca.phd/)

+### Brief Summary of Not-Yet-Supported Query Kinds
+
+The remaining rejects are concentrated in a few recurring categories:
+
+- Non-SQL or shell-like corpus lines mixed into SQL datasets (for example raw text, script fragments, malformed separators).
+- Dialect-specific meta commands or client commands (for example backslash-style command lines in PostgreSQL corpora).
+- Template or parameterized placeholders that are not concrete SQL syntax until preprocessed.
+- Highly dialect-specific operator families and parser corner-cases in advanced analytical or geometric expressions.
+- Intentionally malformed or truncated statements in test corpora (unterminated strings/comments, unexpected EOF).
