Hi @jiaoshuntian, a friendly ping on this one - the Citus integration guide has been open since Oct 17 with CI green and no merge conflicts. It follows the same structure as the other ecosystem component pages (overview, installation, configuration, usage, limitations), and the setup notes were verified against IvorySQL 5.6 with Citus 14.2.0, including the Oracle-mode limitations observed during testing. Would you have a chance to take a look when you are available? Happy to adjust anything. |

Validating plugin compatibility will take some time. The IvorySQL team will provide feedback on this PR as soon as possible. |

CREATE EXTENSION citusfails under the Oracle parser (PostgreSQL-specific syntax such asNO CYCLE), and Oracle-typed tables (NUMBER/VARCHAR2) cannot be distributed because worker-side Citus only runs in a PostgreSQL-mode instance.Checklist
