Materialized view log is one of the feature in oracle. It creates a log in which the changes made to the table are recorded. This log is required for an asynchronous materialized view that is refreshed incrementally.

I read in the below link about incrementally refreshing the materialized view in postgresql:


Can someone let me how to do incremental refresh using Write Ahead Log

Thanks,

Please let me know how to do the incremental refresh of materialized view in postgresql 9.5.9 version.

Is there anything similar to materialized view log in postgresql.


you refresh a materialized view with REFRESH MATERIALIZED VIEW name;    There's no 'incremental' methods, as views can be quite complex.

I do not know what you mean by 'materialized view log', is this a feature of some other database server ?
