I'm using partitioned tables where a child table is chosen based on a

I move records from a temp table to the partitioned table via something like
this:
INSERT INTO parent_table SELECT * FROM temp_table;
All works well but with when inserting to standard tables the insert
result contains the number of records inserted. I've found that when I
insert into partitioned tables the result is always zero.
Are you inserting directly into the partition? Or into the parent table?
If you're inserting into the parent, then it's true that no rows were
inserted into the parent; a trigger redirected the write into the child
table. Pg's handling of partitioning isn't yet sophisticated enough to
recognise that those rows got written to a child and thus still appeared
in the parent and report that.
As a workaround, ignore the insert count for partitioned tables, or
insert directly into the appropriate partition(s).
