PostgreSQL PKGNAME

[Adam <adam%NetBSD.org@localhost>]

Greetings,

Before I commit the update for PostgreSQL packages, I would like to change 
their PKGNAME to postgresql-xxx instead of postgresql90-xxx, postgresql83-xxx, 
postgresql82-xxx. The same way as MySQL packages are named. 

After that, we'll have, for example:
postgresql-server-9.0.2, postgresql-client-9.0.2
NOT: postgresql90-server-9.0.2, postgresql90-client-9.0.2

Any objections?

Kind regards,
Adam
