Hello all
Does anybody know the way to:
1) Get count of elements in postgres array? E.g. for column of
a type TEXT[] for example?
2) Check the column (field) wasn't set during tuple creation? E.g.
CREATE TABLE foo (a INT4, b TEXT);
INSERT INTO foo (b) VALUES ('asdf');
Field 'a' wasn't set, how I can check that in SELECT?
Thanks
