create table style ( ID_STYLE INT4 not null, STYLE_STRING VARCHAR not null, constraint PK_STYLE primary key (ID_STYLE) );
create table style_type_object ( ID_TYPE_OBJECT INT4 not null, ID_STYLE INT4 not null, ZOOMABLE BOOL not null default false, START_SCALE INT4 not null, END_SCALE INT4 not null );
alter table STYLE_TYPE_OBJECT add constraint FK_ID_STYLE foreign key (ID_STYLE) references STYLE (ID_STYLE) on delete restrict on update restrict;
create table style_1 ( constraint PK_STYLE_1 primary key (id_style), check (id_style between 1 and 10000) ) inherits (style);
create rule r_style_1 as on insert to style where (id_style between 1 and 10000) do instead insert into style_1 (id_style, style_string) values(new.id_style, new.style_string);
vka7=# insert into style_type_object values(1, 2, false, 0, 0); ERROR: insert or update on table "style_type_object" violates foreign key constraint "fk_id_style" DETAIL: Key (id_style)=(2) is not present in table "style".
THE QUESTION IS: are there any abilities to check foreign key constraint not only in master table, but also in all tables that inherited the master?
