Re: ERROR: fmgr_info: function 24809: cache lookup failed

You can do without function/trigger, try this :

Create a sequence first :

CREATE SEQUENCE sentenceid_seq;

Create the table:

CREATE TABLE SENTENCES (
SENTENCEID integer DEFAULT NEXTVAL('sentenceid_seq'::text) NOT NULL,
CHAPTERID NUMERIC,
SOFFSET INTEGER,
PRIMARY KEY (SENTENCEID)
);

Besides, I am not sure if DUAL exists in PostgreSQL.
