The grid database has successfully been upgraded from PostgreSQL version 9.4 to 9.6. This is a major upgrade with functionality for parallel queries, better replication technology for both scalability and failover, better text search with support for searching phrases in addition to “hybrid searches” combining relational, JSON, and full text searching
This comes in addition to improvements in version 9.5 with support of features such as UPSERT, row level security and support for much bigger data sets better indexing and faster sorts.
UPSERT means the OpenSim code supporting PostgreSQL can be simplified.
