创建 postgresql 数据库的备份找不到文件

Question

I am on Ubuntu 18.04 and I am using Postgresql database. I ran the command

pg_dump dbname > db.bak

but when I do this, it outputs nothing. I tried to supply a path to the backup and the file does not show up.

My exact commands ran are:

sudo -i -u postgres
psql
pg_dump dbname > db.bak
pg_dump dbname > /db.bak

Answer 1

pg_dump -U myuser -h localhost mydb > db.sql

This worked for me.
