Here is the solution of this problem:
Patch

src/bin/pg_dump/pg_dump.c
appendPQExpBuffer(q, "CREATE TABLE %s (",
fmtId(tbinfo->dobj.name));
actual_atts =3D 0;
for (j =3D 0; j < tbinfo->numatts; j++)
{
/* Is this one of the table's own attrs, and not dropped ? */
- if (!tbinfo->inhAttrs[j] &&
- (!tbinfo->attisdropped[j] || binary_upgrade))
+ if (!tbinfo->attisdropped[j] || binary_upgrade)
{
/* Format properly if not first attr */
if (actual_atts > 0)
appendPQExpBuffer(q, ",");
appendPQExpBuffer(q, "\n ");

Before patch

CREATE TABLE "tmp"."stat_agg_all" (
"foo" BOOLEAN
) INHERITS ("prt4_stat"."stat_data", "prt4_stat"."stat_agg")
WITH OIDS;

After patch:

CREATE TABLE "tmp"."stat_agg_all" (
"foo" BOOLEAN,
"time" TIMESTAMP WITH TIME ZONE NOT NULL,
"banner_views" NUMERIC,
"ad_page_views" NUMERIC,
"phone_validate_views" NUMERIC,
"phone_validate_code_sended" NUMERIC,
"phone_validate_code_validate" NUMERIC,
"ad_form_views" NUMERIC,
"ad_form_submits" NUMERIC,
"ad_shop_select_views" NUMERIC,
"ad_emitted" NUMERIC,
"ad_redeemed" NUMERIC,
"client_payed" NUMERIC,
"mediapartner_charged" NUMERIC,
"ad_banner_views" NUMERIC,
"id" BIGINT NOT NULL,
"interval" "prt4_stat"."stat_enum_interval"
) INHERITS ("prt4_stat"."stat_data", "prt4_stat"."stat_agg")
WITH OIDS;

it well be okey!
