Shinydat: File For Pgsharp Portable

Let me check online for "PGSharp" and see what it is. A quick search shows that PGSharp could be a .NET library for processing PostGIS data, or maybe a tool for managing databases. If it's a database tool, then the .shinydat file could be related to its settings or data files. However, I don't find direct mentions of PGSharp in quick searches. Maybe it's a niche tool or less documented.
