Introduce support for PostgreSQL 18, adding enhanced metrics for checkpointer, vacuum/analyze timings, and parallel worker activity. Implement new collectors for `pg_stat_io` and `pg_backend_memory_contexts` with version-specific queries, along with comprehensive tests. Update README and CI to reflect PostgreSQL 18 compatibility.
Refactored IO and statistics queries to accommodate PostgreSQL 18 features, including byte-level statistics and WAL I/O. Updated tests to validate new columns and ensure query expectation checks are correctly enforced. Improved test coverage across different PostgreSQL versions.
