Sets a callback to be executed each time a statement is run; takes a sub
to this environment variable will not take effect unless you also
re-connect on your schema.
+=head2 DBIC_TRACE_PROFILE
+
+If C<DBIC_TRACE_PROFILE> is set, L<DBIx::Class::Storage::PrettyPrint>
+will be used to format the output from C<DBIC_TRACE>. The value it
+is set to is the C<profile> that it will be used. If the value is a
+filename the file is read with L<Config::Any> and the results are
+used as the configuration for tracing. See L<SQL::Abstract::Tree/new>
+for what that structure should look like.
