Meanwhile, the PostgreSQL ecosystem moved forward to <strong>PostgreSQL 18</strong>, <strong><code>pgrx 0.19.3</code></strong>, and <strong><code>pg_duckdb 1.2.0</code></strong> (which embeds <strong>DuckDB <code>v2.0.0</code></strong>).</p> <p>This article walks through the engineering changes required to bring the entire Mooncake stack — <strong><code>pg_mooncake v0.3.0</code></strong>, <strong><code>duckdb_mooncake v0.0.2</code></strong>, and <strong><code>moonlink v0.0.1</code></strong> — onto <strong>DuckDB <code>2.0.0</code></strong>, <strong><code>pg_duckdb 1.2.0</code></strong>, and <strong><code>pgrx 0.19.3</code></strong>.</p>
