Installing a native version will create a new database.
Upgrading cygwin to 8 will leave you with a non-accessible database.
So if you need the data from the old database, you MUST export it.
See the cygwin announcement, which describes it in detail.
http://article.gmane.org/gmane.os.cygwin.announce/2310
Which says:
Before you upgrade a postgresql package to a new new major or
minor version (7.4 => 8.0 => 8.1 => 8.2), be sure to dump all your data
before!
With the new package you will not be able to access your old databases.
=> http://www.postgresql.org/docs/8.2/static/app-pg-dumpall.html
Minor subrelease updates (e.g. 8.2.4 to 8.2.5) can safely access the
same database.
