I have a schema with a generated table with information coming from batch
processes.
I would like to store in that table manually generated information. Since
those rows are inserted by hand, they will be lost when the table will be
reimported.
So I was thinking of creating a partitioned table with a column "origin" to
select if the data is batch inserted or inserted by hand. Current generated
by batch sub-table will live in its schema.
I want the other sub-table containing manually inserted information living
in another schema.
Is this possible? Do I have to do something else (create some trigger, or
something)?
Something like:
CREATE TABLE *automatic.*measurement (
city_id int not null,
logdate date not null,
peaktemp int,
unitsales int
origin int
) PARTITION BY RANGE (origin);
CREATE TABLE *automatic.*measurement_automatic PARTITION OF
*automatic.*measurement
FOR VALUES FROM (1) TO (1)
PARTITION BY RANGE (origin);
CREATE TABLE *manual.*measurement_manual PARTITION OF *automatic.*measurement
FOR VALUES FROM (2) TO (2)
PARTITION BY RANGE (origin);
