Hi, hackers
When I try to change wal_level to minimal and restart the database, it complains
max_wal_senders > 0.
2022-03-03 10:10:16.938 CST [6389] FATAL: WAL streaming (max_wal_senders > 0) requires wal_level "replica" or "logical"
However, the documentation about wal_level [1] doesn't mentation this.
How about adding a sentence to describe how to set max_wal_senders when
setting wal_level to minimal?
