Using too many fields in an index results in an index name which is being truncated on the db

When this happens Marten will try to drop and regenerate the index every time it starts up. Easily solved by explicitly setting the index name though.

See also Postgres Limits on Naming. Does configuring it this way solve the problem too?

There is also option to set an index name (define a shorter index name) as well while defining the index.
