Problem
when in tried run sql file in psql shell...
give "No such file or directory" error!
$ ls
config.sql config.yaml
$ sudo -i -u postgres psql
postgres=# \i config.sql
config.sql: No such file or directory
thanks for your reply!
Quick solution:
-i => goes to user's home directory!
as result ./config.sql address is incorrect!
just use
$ psql -U <user_name>
postgres=# \i config.sql
sudo -i
