The plpgsql_check is mature project now, and I am would to start discussion about future of this project. It is still private project, although it is important for one from key PostgreSQL feature - PLpgSQL. I would be happy if the community can take some responsibility for this project. This project is too small to create own community and infrastructure like PostGIS.
The development is almost time quiet. There are two issues:
1. It is placed on my personal repository on GitHub. It is far to perfect from security, from substitutability perspective.
2. There is problems with builds for other than Linux platforms. The builds on MS Win are difficult for me, because I don't use Windows.
The plpgsql_check is too big be part of contrib. But I invite some similar, what help me with mentioned issues.
