Re: pg_restore to a port where nobody is listening?

Ok, that makes sense. I got the output on screen, as mentioned.

What I would have expected is at least a hint or warning that host and port are ignored if you do not specify the "-d" switch. Giving port and host clearly indicates that I want to connect to what I provided, doesn't it? psql uses the os username as default database, pg_restore doesn't?

postgres(at)pgbox:/home/postgres/ [PG961] unset PGDATABASE
postgres(at)pgbox:/home/postgres/ [] psql
psql (9.6.1)
Type "help" for help.

(postgres(at)[local]:5439) [postgres] >

Providing "-d" gives a meaningful message at least:

postgres(at)pgbox:/home/postgres/ [PG961] pg_restore -h localhost -p ===6666 -d postgres -F d -C /var/tmp/exp/
pg_restore: [archiver (db)] connection to database "postgres" failed: invalid port number: "===6666"

Maybe it is only me, but this is not consistent behavior, is it?
