[CM8.4.3.201211]Please delete sub partition table in schema for database.

1 Create one table :
CREATE TABLE "pd"(
"i" integer NOT NULL,
"d" date,
CONSTRAINT pk_pd_i PRIMARY KEY("i")
);
ALTER TABLE "pd" PARTITION BY RANGE ([d]) (PARTITION p0 VALUES LESS THAN ('2012-01-01'), PARTITION p1 VALUES LESS THAN ('2013-01-01'));

2 When compare schema for database.
The table ddl will become three tables.
CREATE TABLE "pd"(
"i" integer NOT NULL,
"d" date,
CONSTRAINT pk_pd_i PRIMARY KEY("i")
);
ALTER TABLE "pd" PARTITION BY RANGE ([d]) (PARTITION p0 VALUES LESS THAN ('2012-01-01'), PARTITION p1 VALUES LESS THAN ('2013-01-01'));

CREATE TABLE "pd_p_p0"
UNDER "pd";

CREATE TABLE "pd_p_p1"
UNDER "pd";

Suggest delete the sub table of partition table.
