That is expected when you parameterize a query - the query string includes
parameters instead of values. What you are seeing is the "Prepare"
component of a "prepare-execute". When you execute you then see something
like; "execute unnamed_query ['pg_database']" (note, I'm not familiar with
the exact syntax and terminology that would appear in the log file).
