chore(deps): bump pg_query from 6.1.0 to 6.2.1

[dependabot]

Bumps pg_query from 6.1.0 to 6.2.1.

Changelog

Sourced from pg_query's changelog.

6.2.1 2026-01-20

• Upgrade to libpg_query 17-6.2.1
  • Add pg_query_is_utility_stmt function to determine if query text contains utility statements #313
    • This is a fast check for callers that don't actually need the parse tree itself
  • Add fast summary information function (pg_query_summary)
    • This allows gathering certain information, for example which tables are referenced in a statement, without requiring a Protobuf serialization step in a higher level library
    • Additionally this can also be used to perform "smart truncation" of a query by omitting deeply nested information (e.g. a CTE definition, or a target list) whilst preserving more essential parts like the FROM clause
  • Deparser:
    • Introduce pretty printing / formatting
      • Introduces a new optional pretty print mode that emits a human readable output. A detailed explanation of the mechanism can be found at the start of the deparser file.
    • Rework handling of expressions inside typecasts
      • Prefer (..)::type syntax, unless we are already in a function call.
    • Use lowercase keywords in xmlroot functions
      • This matches other XML functions as well as the Postgres documentation, since these are closer to function argument names than regular keywords.
    • Fix deparse of ALTER TABLE a ALTER b SET STATISTICS DEFAULT
    • Fix the null pointer dereference when handling identity columns
  • Allow alternate definitions of NAMEDATALEN identifier limit
    • This allows building libpg_query with an override of the built-time limit of Postgres identifiers (typically 63 characters)
  • Normalization: Add support for CALL statements
  • Bump Postgres to 17.7 and switch back to release tarballs
• Deparser: Support pretty-printing and other deparser options
  • PgQuery::ParserResult#deparse now takes options like pretty_print
• Add PgQuery.split_with_parser method to allow splitting statements
• Support Ruby 4.0+ development versions for extension building
• Fix ABI version error with TruffleRuby on Mac
• Support finding functions invoked with CALL
• Support null_test and boolean_test node type with parsing
• Expose PgQuery::ParserResult#find_tree_location method
