thanks. I downloaded the patches from the postgres website, then the
problem was solved.
other ideas based on v29.
src/include/utils/rel.h
680: #define RelationIsIVM(relation) ((relation)->rd_rel->relisivm)
I guess it would be better to add some comments to address the usage.
Since all peer macros all have some comments.
pg_class change, I guess we need bump CATALOG_VERSION_NO?
small issue. makeIvmAggColumn and calc_delta need to add an empty
return statement?
style issue. in gram.y, "incremental" upper case?
+ CREATE OptNoLog incremental MATERIALIZED VIEW
create_mv_target AS SelectStmt opt_with_data
I don't know how pgident works, do you need to add some keywords to
src/tools/pgindent/typedefs.list to make indentation work?
in
/* If this is not the last AFTER trigger call, immediately exit. */
Assert (entry->before_trig_count >= entry->after_trig_count);
if (entry->before_trig_count != entry->after_trig_count)
return PointerGetDatum(NULL);
before returning NULL, do you also need clean_up_IVM_hash_entry? (I
don't know when this case will happen)
in
/* Replace the modified table with the new delta table and
calculate the new view delta*/
replace_rte_with_delta(rte, table, true, queryEnv);
refresh_matview_datafill(dest_new, query, queryEnv, tupdesc_new, "");
replace_rte_with_delta does not change the argument: table, argument:
queryEnv. refresh_matview_datafill just uses the partial argument of
the function calc_delta. So I guess, I am confused by the usage of
replace_rte_with_delta. also I think it should return void, since you
just modify the input argument. Here refresh_matview_datafill is just
persisting new delta content to dest_new?
