drop maintainership of databases/pg_reorg, databases/postgresql-repmgr

[Alexander Pyhalov]

Hello.
We don't use FreeBSD on our database server longer. Besides, I became 
tightly involved in OpenIndiana development and just don't have time 
enough to support FreeBSD ports I've created, so I'd like to drop 
manitainership for databases/pg_reorg, databases/postgresql-repmgr.
I think it would be honest, because I just can't support them on 
adequate level.
