dependabot[bot] opened a new pull request, #2795: URL: https://github.com/apache/datafusion-sqlparser-rs/pull/2795
Bumps [pg_query](https://github.com/pganalyze/pg_query.rs) from 6.2.1 to 18.1.0. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/pganalyze/pg_query.rs/blob/main/CHANGELOG.md";>pg_query's changelog</a>.</em></p> <blockquote> <h2>18.1.0 2026-10-27</h2> <ul> <li>Upgrade to Postgres 18.6 (libpg_query 18.1.0) <ul> <li>Performance: libpg_query now uses upb instead of protobuf-c for serialization, which is substantially faster thanks to its built-in arena allocation, resulting in 2x faster runtime.</li> <li>Robustness: overly deep queries now return a "stack depth limit exceeded" error instead of crashing the process (<a href="https://redirect.github.com/pganalyze/libpg_query/pull/348";>#348</a>), and the deparser strictly checks unexpected pointer values in input parse trees instead of crashing</li> <li>Parser: comments are now ignored when parsing queries (they are only significant for scanning), fixing parse errors for tokens like <code>NOT /* comment */ IN</code> (<a href="https://redirect.github.com/pganalyze/libpg_query/pull/378";>#378</a>); PL/pgSQL statements without bodies now return an error instead of crashing (<a href="https://redirect.github.com/pganalyze/libpg_query/pull/363";>#363</a>)</li> <li>Parser: PL/pgSQL parsing reworked to use proper type definitions (Postgres 18.0.0), replacing the previous ad-hoc approach</li> <li>Deparser: parentheses are now added based on operator precedence, fixing cases where deparsed SQL changed meaning or was invalid (<a href="https://redirect.github.com/pganalyze/libpg_query/pull/371";>#371</a>)</li> <li>Deparser: comment handling reworked for Postgres 18 multi-statement strings: comments between statements are no longer attributed to the following statement (relevant for <code>deparse_comments_for_query</code>)</li> <li><code>normalize</code>: support <code>NOTIFY</code> statements (<a href="https://redirect.github.com/pganalyze/libpg_query/pull/340";>#340</a>) and fix handling of <code>U&</code> special constants in <code>DefElem</code> nodes (<a href="https://redirect.github.com/pganalyze/libpg_query/pull/347";>#347</a>)</li> <li><code>summary</code>: fix a relation going missing when a CTE shares its name (<a href="https://redirect.github.com/pganalyze/libpg_query/pull/367";>#367</a>) and fix a memory leak when the tree walk throws an error</li> </ul> </li> <li><strong>Breaking</strong>: <code>parse</code>, <code>fingerprint</code> and <code>summary</code> now require parser/fingerprint options arguments, corresponding to the C <code>pg_query_parse_opts</code>, <code>pg_query_fingerprint_opts</code> and <code>pg_query_summary</code> APIs. Options accept <code>ParserOptions</code>/<code>FingerprintOptions</code> constants or raw integers; pass <code>0</code> for the defaults: <ul> <li><code>parse(statement, parser_options)</code></li> <li><code>fingerprint(statement, parser_options, fingerprint_options)</code></li> <li><code>summary(statement, parser_options, truncate_limit)</code></li> </ul> </li> <li><strong>Breaking</strong>: <code>deparse</code> now requires a <code>DeparseOptions</code> argument, and all <code>deparse</code> convenience methods (<code>ParseResult::deparse</code>, <code>protobuf::ParseResult::deparse</code>, <code>Node::deparse</code>, <code>NodeEnum::deparse</code>, <code>NodeRef::deparse</code>, <code>NodeMut::deparse</code>) likewise require it, mirroring the C <code>PostgresDeparseOpts</code> struct (comments, pretty_print, indent_size, max_line_length, trailing_newline, commas_start_of_line); pass <code>Default::default()</code> for the previous plain behavior</li> <li>Fingerprint values changed: fingerprinting now follows Postgres 18 query ID behavior. In SELECT/DML statements the relation alias (if present) replaces the relation name and schema names are ignored; sequences of 2+ digits</li> </ul> <!-- raw HTML omitted --> </blockquote> <p>...
