Fixed #19968 -- Dropped support for PostgreSQL < 8.4.
Update versions and links to source tarballs.
Fixed #13260 -- Quoted arguments interpolated in URLs in reverse.
Added warn note to docs about MySQL issues with 0000-00-00 date strings

MySQL accepts 0000-00-00 as a valid date but MySQLdb converts those
values into None. So there will be problems for instance if trying to
transport the data using dumpdata/loaddata.

This patch refs #6642 that has been closed as wontfix since this is a
particular problem of MySQL.
