If I take out that patch, pglogical_create_subscriber seems to start
postgres on the default port (5432), without looking at subscriber-dsn,
so I'm unsure it would work for your 5433 port. Did you test it with
upstream pglogical and/or how is this supposed to work?

I get a process with
"/usr/lib/postgresql/12/bin/pglogical_create_subscriber -D
/tmp/regresscheck.R5THTZ/tmp_check/tmp_backupdir --subscriber-
name=test_subscriber --subscriber-
dsn=host=/tmp/regresscheck.R5THTZ/tmp_check/tmp_socketdir user=super
port=65432 dbname=postgres --provider-
dsn=host=/tmp/regresscheck.R5THTZ/tmp_check/tmp_socketdir user=super
port=65431 dbname=postgres --drop-slot-if-exists -v --hba-conf=regress-
pg_hba.conf --postgresql-
conf=/tmp/regresscheck.R5THTZ/tmp_check/tmp_datadir/postgresql.conf"

but in /tmp/regresscheck.R5THTZ/tmp_check/tmp_socketdir the sockets are:

.s.PGSQL.5432 .s.PGSQL.5432.lock .s.PGSQL.65431 .s.PGSQL.65431.lock

and the t/010_pglogical_create_subscriber.pl TAP test hangs.
