Re: Implementing Incremental View Maintenance - Mailing list pgsql-hackers

Hello,
Thank you for this patch.

I have tried to use an other patch with yours:
"Planning counters in pg_stat_statements (using pgss_store)"
https://www.postgresql.org/message-id/CAOBaU_Y12bn0tOdN9RMBZn29bfYYH11b2CwKO1RO7dX9fQ3aZA%40mail.gmail.com

setting
shared_preload_libraries='pg_stat_statements'
pg_stat_statements.track=all
and creating the extension


When trying following syntax:

create table b1 (id integer, x numeric(10,3));
create incremental materialized view mv1 as select id, count(*),sum(x) from
b1 group by id;
insert into b1 values (1,1)

I got an ASSERT FAILURE in pg_stat_statements.c
on
    Assert(query != NULL);

comming from matview.c
    refresh_matview_datafill(dest_old, query, queryEnv, NULL);
or
    refresh_matview_datafill(dest_new, query, queryEnv, NULL);


If this (last) NULL field was replaced by the query text, a comment or just
"n/a",
it would fix the problem.

Could this be investigated ?

Thanks in advance
Regards
PAscal
