I am in the design phase of a new db so I cannot test queries using
explain/analyze yet, but regarding performance, is there any
difference in doing this:
CREATE TABLE something (name text, age smallint, ...other columns...,
comment text);
compared to this:
CREATE TABLE comments (id serial primary key, comment text);
CREATE TABLE something (name text, age smallint, ...other columns...,
comment integer REFERENCES comments(id));
?
The comments field will be used here and there but I expect it will
most often be NULL.
