 The PostgreSQL Global Development Group recognizes that while PostgreSQL itself contains a robust set of features, not all of them may be easy-to-use and could require workarounds in both development and production environments.
 
-Prior to PostgreSQL 11, one such feature was using the `ALTER TABLE .. ADD COLUMN` command where the newly created column contained a `NOT NULL DEFAULT` value. Prior to PostgreSQL 11, when executing aforementioned statement, PostgreSQL would rewrite the whole table, which on larger tables in active systems could cause a cascade of problems. PostgreSQL 11 removes the need to rewrite the table, and as such running `ALTER TABLE .. ADD COLUMN .. NOT NULL DEFAULT ..` will execute extremely quickly.

 Another feature that fell into this category was the inability to intuitively quit from the PostgreSQL command-line (`psql`). There has been numerous recorded complaints of users trying to quit with the `quit` and `exit` commands, only to learn that the command to do so was `\q` (or _Ctrl-D_ if someone was so inclined).
