| 170 | | # A single PostgreSQL connection can only perform a single query at a time, |
|---|
| 171 | | # which is an important restriction to note. This limitation can be overcome |
|---|
| 172 | | # by retrieving all results immediately after a query, but this approach is not |
|---|
| 173 | | # taken by this library. |

| | 170 | # The database connection is derived from the {@link #Cursor Cursor} class, and |
|---|
| | 171 | # provides access to the database's unnamed cursor through the standard Cursor |
|---|
| | 172 | # methods. It also provides transaction control via the 'begin', 'commit', and |
|---|
| | 173 | # 'rollback' methods. Without beginning a transaction explicitly, all |
|---|
| | 174 | # statements will autocommit to the database. |
