What are these Unknown connections in my query queue?

In the Admin > Database > Queries panel, sometimes we will see queries made to an unknown database without any information on the query.

Usually these queries to "unknown" connections are placeholders for merged result queries. If a tile has results from two separate connections, we see 3 different events in the query panel. One placeholder (“unknown”), then two actual queries (with known connections listed).
