Bug reference: 15603

PostgreSQL version: 11.1
Operating system: Linux
Description:
When I look at the LibPQ documentation I don't see replication (which I
*think* can be true or database) listed as a valid option.
I would expect that it would be listed here:
https://www.postgresql.org/docs/11/libpq-connect.html#LIBPQ-PARAMKEYWORDS
It *is* mentioned in passing here:
https://www.postgresql.org/docs/11/protocol-replication.html
And it obviously works!
