Re: Declarative partitioning - another take

Hi Amit,

I have pulled latest sources from git and tried to create multi-level
partition, getting a server crash, below are steps to reproduce. please
check if it is reproducible in your machine also.

postgres=# CREATE TABLE test_ml (a int, b int, c varchar) PARTITION BY
RANGE(a);
CREATE TABLE
postgres=# CREATE TABLE test_ml_p1 PARTITION OF test_ml FOR VALUES FROM (0)
TO (250) PARTITION BY RANGE (b);
CREATE TABLE
postgres=# CREATE TABLE test_ml_p1_p1 PARTITION OF test_ml_p1 FOR VALUES
FROM (0) TO (100);
CREATE TABLE
postgres=# CREATE TABLE test_ml_p1_p2 PARTITION OF test_ml_p1 FOR VALUES
FROM (100) TO (250);
CREATE TABLE
postgres=# CREATE TABLE test_ml_p2 PARTITION OF test_ml FOR VALUES FROM
(250) TO (500) PARTITION BY RANGE (c);
CREATE TABLE
postgres=# CREATE TABLE test_ml_p2_p1 PARTITION OF test_ml_p2 FOR VALUES
FROM ('0250') TO ('0400');
CREATE TABLE
postgres=# CREATE TABLE test_ml_p2_p2 PARTITION OF test_ml_p2 FOR VALUES
FROM ('0400') TO ('0500');
CREATE TABLE
postgres=# CREATE TABLE test_ml_p3 PARTITION OF test_ml FOR VALUES FROM
(500) TO (600) PARTITION BY RANGE ((b + a));
CREATE TABLE
postgres=# CREATE TABLE test_ml_p3_p1 PARTITION OF test_ml_p3 FOR VALUES
FROM (1000) TO (1100);
CREATE TABLE
postgres=# CREATE TABLE test_ml_p3_p2 PARTITION OF test_ml_p3 FOR VALUES
FROM (1100) TO (1200);
CREATE TABLE
postgres=# INSERT INTO test_ml SELECT i, i, to_char(i, 'FM0000') FROM
generate_series(0, 599, 2) i;
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.
