Hello,
I tried this feature using most recently snapshot. In case of added constraint
PRIMARY KEY for partition table, INSERT ON CONFLICT DO NOTHING statement failed
with segmentaion fault.
If the primary key constraint was not created on the partition, this statement
executed successfully.
- Test
postgres=> CREATE TABLE part1(c1 NUMERIC, c2 VARCHAR(10)) PARTITION BY RANGE
(c1) ;
CREATE TABLE
postgres=> CREATE TABLE part1p1 PARTITION OF part1 FOR VALUES FROM (100) TO
(200) ;
CREATE TABLE
postgres=> ALTER TABLE part1p1 ADD CONSTRAINT pk_part1p1 PRIMARY KEY (c1) ;
ALTER TABLE
postgres=> INSERT INTO part1 VALUES (100, 'init') ON CONFLICT DO NOTHING ;
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
