Summary

This PR updates the sqlparser dev-dependency from version 0.61 to 0.62. The change is minimal (only Cargo.toml and Cargo.lock modified) and appears to be a routine dependency upgrade.

Verdict: Approve - This is a safe, non-breaking update that requires no code changes.

Research notes

I reviewed the sqlparser 0.62.0 changelog which contains 79 commits from 27 contributors. Key observations:

• No breaking changes affecting this codebase: The API used in this repository (PostgreSqlDialect {} struct construction and Parser::parse_sql()) remains stable
• PostgreSQL-specific enhancements: The release includes several PostgreSQL improvements (PRIMARY KEY/UNIQUE USING INDEX, COMMENT ON object types, LOCK TABLE, LATERAL ... WITH ORDINALITY, etc.), but these are additive features
• Bug fixes: Includes fixes for panics in incomplete expressions and error handling improvements
• One noted breaking change: "Resolve breaking change that set 'supports_lambda_functions' on GenericDialect" - this does not affect PostgreSqlDialect usage

Codebase impact analysis

The sqlparser crate is only used in test code (#[cfg(test)]) in src/repository.rs:375:

use sqlparser::{dialect::PostgreSqlDialect, parser::Parser};

fn validate_sql(sql: &str) -> Result<(), String> {
    let dialect = PostgreSqlDialect {};
    Parser::parse_sql(&dialect, sql)
        .map_err(|e| format!("SQL parse error: {e}"))
        .map(|_| ())
}

This is the standard, stable API that has not changed between versions. The production code has zero dependency on sqlparser.

Suggested next steps

1. Merge this PR - The update is safe and brings bug fixes and improvements
2. Verify CI passes - Ensure cargo test and cargo clippy pass in CI (Rust toolchain not available in review environment to verify locally)

General findings

No issues identified. This is a well-scoped dependency update with:

• ✅ Minimal surface area (dev-dependency only)
• ✅ Stable API usage pattern
• ✅ No breaking changes for the specific usage in this codebase
• ✅ Benefits from upstream bug fixes and PostgreSQL dialect improvements
