I'm running a fairly large sql script (aprox 300k insert statements) against a postgres database and I'm getting a 'no space left on device' error.
I know this error means there isn't enough disk space for postgres to complete the operation, but the odd thing is that if I split the file into 10 pieces and run each one individually it completes without any error, and once all the rows are inserted there is still plenty of disk space left over.
The sql script creates a few tables and then has thousands of individual insert statements, and then creates some indexes at the end. I've left the default auto-commit behaviour in place, I know this isn't optimal from a performance point of view but that's not an issue for me in this case.
Does postgres create some temporary files while processing a sql script that might be causing the issue?
Not sure it's relevant but I'm running the script via ansible, and the postgres db is in a docker container.
