listen_addresses (string)
Specifies the TCP/IP address(es) on which the server is to listen for
connections from client applications. The value takes the form of a
comma-separated list of host names and/or numeric IP addresses. (...)

I tried different versions of names and IPs, quoted in single, double and no
quotes at all, comma separated between quotes and inside, like
<quote>
listen_addresses = '192.168.32.3','127.0.0.1'
# or
listen_addresses = '192.168.32.3,127.0.0.1'
</quote>
Any parameter that has a string type are enclosed in single quotes [1]. Hence,
a list of addresses consists of
listen_addresses = 'W, X, Y, Z'
gives me:

You use double quotes for each individual address.

You are using double quotes. It would work if you just replaced it with single
quotes.

Again, you are using multiple strings separated by comma instead of just
one string.

So I tried to follow the otherwise seen pattern and wrote into
postgresql.conf:
<quote>
listen_addresses = '192.168.32.3'
listen_addresses = '127.0.0.1'
</quote>
which worked.
It worked but it is just listening to 127.0.0.1.
$ tail -n 2 $PGDATA/postgresql.conf
listen_addresses = '192.168.32.3'
