Right. From a user's perspective 4) sounds best. I often run into problems
having keywords as column-names:
andreak=# create table test(user varchar);
ERROR: syntax error at or near "user"
LINE 1: create table test(user varchar);
^
andreak=# create table test("user" varchar);
CREATE TABLE
andreak=# insert into test("USER") values('testuser');
ERROR: column "USER" of relation "test" does not exist
LINE 1: insert into test("USER") values('testuser');
^
andreak=# insert into test(user) values('testuser');
ERROR: syntax error at or near "user"
LINE 1: insert into test(user) values('testuser');
^
andreak=# insert into test("user") values('testuser');
INSERT 0 1
As you know, the only way of referring to the "user"-column is to qoute it in
lowercase, which many apps and tools don't do.
