Problem reproduced here with exactly the same stack. Here is a simple
SQL sequence:
create table aa (a int);
create materialized view aam as select * from aa;
create unique index aami on aam(a);
insert into aa values (generate_series(1,100000));
refresh materialized view CONCURRENTLY aam;

I have added an open item.
