Bug reference:      16553
Logged by:          Giorgio Saviane
Email address:      gsaviane@gmail.com
PostgreSQL version: 11.8
Operating system:   Linux
Description:

now() and transaction_timestamp() are described as being equivalent in the
guide
https://www.postgresql.org/docs/11/functions-datetime.html#FUNCTIONS-DATETIME-CURRENT.
However, using now() in a query can screw up a possible parallel plan since
it's labeled PARALLEL RESTRICTED.
