Subject: [PATCH 1/5] feat(postgresql): add accurate analyzer mode for
 database-only analysis
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add an optional `analyzer.accurate: true` mode for PostgreSQL that bypasses
the internal catalog and uses only database-backed analysis.

Key features:
- Uses database PREPARE for all type resolution (columns, parameters)
- Uses expander package for SELECT * and RETURNING * expansion
- Queries pg_catalog to build catalog structures for code generation
- Skips internal catalog building from schema files

Configuration:
```yaml
sql:
  - engine: postgresql
    database:
      uri: "postgres://..."  # or managed: true
    analyzer:
      accurate: true
```

This mode requires a database connection and the schema must exist in the
database. It provides more accurate type information for complex queries.

Subject: [PATCH 2/5] test: add end-to-end tests for accurate analyzer mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add three end-to-end test cases for the accurate analyzer mode:

1. accurate_star_expansion - Tests SELECT *, INSERT RETURNING *, UPDATE RETURNING *, DELETE RETURNING *
2. accurate_enum - Tests enum type introspection from pg_catalog
3. accurate_cte - Tests CTE (Common Table Expression) with star expansion

All tests use the managed-db context which requires Docker to run
PostgreSQL containers.

Subject: [PATCH 3/5] fix(tests): update expected output for accurate mode
 end-to-end tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update expected output files to match actual sqlc generate output:
- Fix parameter naming (Column1, Column2, dollar_1)
- Fix nullability types (sql.NullString, sql.NullInt32)
- Fix CTE formatting (single line)
- Fix query semicolons

Subject: [PATCH 5/5] fix(ast): fix VALUES clause formatting to output multiple
 rows
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The VALUES clause was incorrectly formatting multiple rows as a single
row with multiple columns. For example:
  VALUES ('A'), ('B'), ('C')
was being formatted as:
  VALUES ('A', 'B', 'C')

This caused the star expander to think the VALUES table had 3 columns
instead of 1, resulting in incorrect SELECT * expansion.

The fix properly iterates over each row in ValuesLists and wraps each
in parentheses.
