Prior to PostgreSQL 11, one such feature was using the `ALTER TABLE .. ADD COLUMN` command where the newly created column had a `DEFAULT` value that was not NULL. 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 in most cases, and as such running `ALTER TABLE .. ADD COLUMN .. 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).

We have heard your frustrations and have now added the ability to quit the command-line using the keywords `quit` and `exit` and hope that quitting a PostgreSQL session is now as enjoyable as using PostgreSQL.
