Refresh materialized views with concurrency

Question

I have a PostgreSQL DB, where I use materialized views. The problem occurs when I try to refresh these materialized views.

REFRESH MATERIALIZED VIEW produc         


        

Answer 1

You will have to create a unique index on the materialized view itself.

This would look like this:

CREATE UNIQUE INDEX ON productsforproject (id);

Replace id with a suitable unique key column or a (comma separated) combination of such columns.
