title: Npgsql 6.x: How to find type mapping for CLR Type
body: <p>In one of my projects I'm migrating Npgsql from 5.x to 6.x and I noticed that Npgsql.NpgsqlConnection.GlobalTypeMapper is missing Mapping property.</p>
  <p>In 5.x I was using this property to find CLR type and get it's mapping to Postgres Type Name (PgTypeName).
  Now (in 6.x), when Mappings property is gone, I need to do it in other way. So, how it is possible in Npgsql 6.x to map CLR Type to Postgres Type Name?</p>
