The syntax of the psql command line client is
psql [option...] [dbname [username]]
I am passing the command ALTER DATABASE x RENAME to y to this command:
echo `ALTER DATABASE x RENAME to y` | psql
Currently I am getting the error
psql: FATAL: database "myuser" does not exist
It looks like the psql command tries to open the database with the same name as the current user name.
How can I start the psql command without selecting any database?
Edit:
A workaround is of course just to create an empty database for the user.
Using the database x as a parameter is not working, as this blocks the rename.

Try setting the database: psql -d postgres:
echo `ALTER DATABASE x RENAME to y` | psql -d postgres
"template1" or "postgres" should be available.
See
In Ubuntu:
sudo -u postgres psql
postgres=# ALTER DATABASE "old" RENAME TO "new";
ALTER DATABASE
postgres=# \q
