The default value of the parallel_tuple_cost parameter is 0.1. The value of the parallel_tuple_cost variable of pg_hint_plan is changed from 0.1 to 0 because it is of type int. This is why the execution plan changes in parallel when using pg_hint_plan.

Thank you for the report. Fixed by the commit 7dcc96f at master and back-patched up to PG95 branch.
