This is not a bug, at least not in Postgresql.

I'm surprised you didn't get a syntax error if that really is your 
insert statement. If you use double quotes (") then you are referring to 
a column name. If you want to insert a string you need to use single 
quotes (').

e.g.

INSERT INTO sentence (citation_id, sen_offset, sen_length, sen_type) 
VALUES (1,2,3,'asd');

However, I see you have declared sen_type as an array. Again if this was 
intentional you need to specify an array value of some kind to fill it.

e.g.

INSERT INTO sentence (citation_id, sen_offset, sen_length, sen_type) 
VALUES (1,2,3,'{asd}');

Notice also that sentence_id must be omitted from the insert as it is a 
serial column.

I think you also need to read the manual more closely regarding arrays, 
insert statements, strings and serial columns!


Cheers,
