Add the database name to the ps display of logical WAL senders 

Logical WAL senders display now as follows, gaining a database name:
postgres: walsender USER DATABASE HOST(PORT) STATE

Physical WAL senders show up the same, as of:
postgres: walsender USER HOST(PORT) STATE

This information was missing, hence it was not possible to know from ps
if a WAL sender was a logical or a physical one, and on which database
it is connected when it is logical.
