On more or less HEAD:
$ psql -X -d "replication=1 dbname=postgres"
postgres=# create table aa (a int);
ERROR: cannot execute SQL commands in WAL sender for physical replication
$ psql -X -d "replication=database dbname=postgres"
postgres=# create table aa (a int);
CREATE TABLE
So one needs to use replication=database in order to be able to issue
normal SQL statements, while replication=true enforces physical
replication where this cannot happen (no connection to a specified
database).
