the first connection.

- Set library version to 2.7.1

- Added 'at <db_connection>' option to all commands it is apllicable
|
||||
to. Due to changing the API of some libecpg functions this
|
||||
requires me to increase the major version number.
|
||||
- Synced pgc.l with scan.l.
|

- Added support for unions.
|

- Set library version to 3.0.0

'at DB connection' is missing for several commands (is this standard?)
