t_node see above and in addition t_document:
CREATE TABLE t_document (
doc_id int4 DEFAULT nextval('seq_document') NOT NULL ,
doc_content_id int4,
doc_lr_id int4 NOT NULL ,
doc_url text NULL ,
doc_start int4,
doc_end int4,
doc_is_markup_aware bool NOT NULL ,
FOREIGN KEY ( doc_content_id )
REFERENCES t_doc_content ( dc_id )
MATCH FULL ,
FOREIGN KEY ( doc_lr_id )
REFERENCES t_lang_resource ( lr_id )
MATCH FULL ,
PRIMARY KEY ( doc_id )
);
CREATE UNIQUE INDEX xt_document_01 on t_document (doc_lr_id);
