问题
When trying to run a SQL script using psql I am getting permission denied error.
Steps followed -
- opened up normal Bash interactive shell
- Ran the command as below
sudo -u postgres -s /bin/bash
- tried running the below pgsql - I provided the read write access to the pega folder; what else needs to be done to move the pgsql file to postgres library.
/Library/PostgreSQL/12/bin/psql -U dbusername dbpassword </Users/rr/Documents/pega/pega8db.pgsql
got the below error
bash: /Users/rr/Documents/pega/pega8db.pgsql: Permission denied

First: check permissions for the file itself:
ls -al /Users/rr/Documents/pega/pega8db.pgsql
then you can add read & execute permissions by doing:
sudo chmod a+rx /Users/rr/Documents/pega/pega8db.pgsql (this will give read to everyone, so if its multiuser system, you may want to revert perms later).
Are you able to connect to database using the psql tool and get the psql prompt, or is that failing too?
I assume that your .pgsql file is essentially sql script, right (some kind of export)?
Try to run like this:
psql -d database_name -a -f /Users/rr/Documents/pega/pega8db.pgsql
