Issues for partitions and subpartitions migration

[AyUser84]

Hello,
I have this Oracle table to migrate :

CREATE TABLE <TABLE_NAME> (
LOADING_MONTH DATE NOT NULL,
COL2
COL3
...
COLN
)
TABLESPACE XX
NOLOGGING
PARTITION BY RANGE (LOADING_MONTH) INTERVAL(NUMTOYMINTERVAL(1, 'MONTH'))
SUBPARTITION BY RANGE (COL2)
SUBPARTITION TEMPLATE
(
SUBPARTITION SUBPART_0 values LESS THAN(1),
SUBPARTITION SUBPART_1 values LESS THAN(2),
SUBPARTITION SUBPART_2 values LESS THAN(3),
SUBPARTITION SUBPART_3 values LESS THAN(4),
SUBPARTITION SUBPART_4 values LESS THAN(5),
SUBPARTITION SUBPART_5 values LESS THAN(6),
SUBPARTITION SUBPART_6 values LESS THAN(7),
SUBPARTITION SUBPART_7 values LESS THAN(8),
SUBPARTITION SUBPART_8 values LESS THAN(9),
SUBPARTITION SUBPART_9 values LESS THAN(10),
SUBPARTITION SUBPART_10 values LESS THAN(MAXVALUE)
)
( PARTITION LOADING_MONTH_HIS_DATA VALUES LESS THAN (TO_DATE(' 2024-01-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))) ;

Using ora2pg version 24.3 for migration have this as result :

CREATE TABLE LOADING_MONTH_HIS_DATA PARTITION OF TABLE_NAME
FOR VALUES FROM (MINVALUE) TO (' 2024-01-01 00:00:00')
PARTITION BY RANGE (COL2);
CREATE TABLE TABLE_NAME_LOADING_MONTH_HIS_DATA_subpart_0 PARTITION OF LOADING_MONTH_HIS_DATA
FOR VALUES FROM (MINVALUE) TO (1);
CREATE TABLE TABLE_NAME_LOADING_MONTH_HIS_DATA_subpart_1 PARTITION OF LOADING_MONTH_HIS_DATA
FOR VALUES FROM (MINVALUE) TO (2);
CREATE TABLE TABLE_NAME_LOADING_MONTH_HIS_DATA_subpart_2 PARTITION OF LOADING_MONTH_HIS_DATA
FOR VALUES FROM (MINVALUE) TO (3);
CREATE TABLE TABLE_NAME_LOADING_MONTH_HIS_DATA_subpart_3 PARTITION OF LOADING_MONTH_HIS_DATA
FOR VALUES FROM (MINVALUE) TO (4);
CREATE TABLE TABLE_NAME_LOADING_MONTH_HIS_DATA_subpart_4 PARTITION OF LOADING_MONTH_HIS_DATA
FOR VALUES FROM (MINVALUE) TO (5);
CREATE TABLE TABLE_NAME_LOADING_MONTH_HIS_DATA_subpart_5 PARTITION OF LOADING_MONTH_HIS_DATA
FOR VALUES FROM (MINVALUE) TO (6);
CREATE TABLE TABLE_NAME_LOADING_MONTH_HIS_DATA_subpart_6 PARTITION OF LOADING_MONTH_HIS_DATA
FOR VALUES FROM (MINVALUE) TO (7);
CREATE TABLE TABLE_NAME_LOADING_MONTH_HIS_DATA_subpart_7 PARTITION OF LOADING_MONTH_HIS_DATA
FOR VALUES FROM (MINVALUE) TO (8);
CREATE TABLE TABLE_NAME_LOADING_MONTH_HIS_DATA_subpart_8 PARTITION OF LOADING_MONTH_HIS_DATA
FOR VALUES FROM (MINVALUE) TO (9);
CREATE TABLE TABLE_NAME_LOADING_MONTH_HIS_DATA_subpart_9 PARTITION OF LOADING_MONTH_HIS_DATA
FOR VALUES FROM (MINVALUE) TO (10);
CREATE TABLE LOADING_MONTH_HIS_DATA_subpart_10 PARTITION OF TABLE_NAME DEFAULT;
CREATE TABLE sys_p663 PARTITION OF TABLE_NAME
FOR VALUES FROM (' 2024-01-01 00:00:00') TO (' 2025-11-01 00:00:00')
PARTITION BY RANGE (COL2);
CREATE TABLE TABLE_NAME_sys_subp563 PARTITION OF sys_p663
FOR VALUES FROM () TO (1);
CREATE TABLE TABLE_NAME_sys_subp564 PARTITION OF sys_p663
FOR VALUES FROM (1) TO (2);
CREATE TABLE TABLE_NAME_sys_subp565 PARTITION OF sys_p663
FOR VALUES FROM (2) TO (3);
CREATE TABLE TABLE_NAME_sys_subp566 PARTITION OF sys_p663
FOR VALUES FROM (3) TO (4);
CREATE TABLE TABLE_NAME_sys_subp567 PARTITION OF sys_p663
FOR VALUES FROM (4) TO (5);
CREATE TABLE TABLE_NAME_sys_subp568 PARTITION OF sys_p663
FOR VALUES FROM (5) TO (6);
CREATE TABLE TABLE_NAME_sys_subp569 PARTITION OF sys_p663
FOR VALUES FROM (6) TO (7);
CREATE TABLE TABLE_NAME_sys_subp570 PARTITION OF sys_p663
FOR VALUES FROM (7) TO (8);
CREATE TABLE TABLE_NAME_sys_subp571 PARTITION OF sys_p663
FOR VALUES FROM (8) TO (9);
CREATE TABLE TABLE_NAME_sys_subp572 PARTITION OF sys_p663
FOR VALUES FROM (9) TO (10);
CREATE TABLE sys_subp573 PARTITION OF inettsegmentation_pyramide_stock DEFAULT;

1 - for the TABLE_NAME_LOADING_MONTH_HIS_DATA_subpart_XX part, why he use (MINVALUE) TO (number) and not the interval everytime ((MINVALUE) TO (2) (MINVALUE) TO (3) and not (1) TO (2) (2) TO (3) )
2- for the CREATE TABLE TABLE_NAME_sys_subp563 PARTITION OF sys_p663 FOR VALUES FROM () TO (1); MINVALUE is missing
3- for the last partition creation : CREATE TABLE sys_subp573 PARTITION OF inettsegmentation_pyramide_stock DEFAULT , isn't rather CREATE TABLE TABLE_NAME_sys_subp573 PARTITION OF sys_p663
FOR VALUES FROM (10) TO (MAXVALUE) ?

Thank you for your reply
