Postgres wants to create a
$HOME/.psql_history file, where it will store all your queries and commands from the
psql client. It may well want to do something else at
$HOME, but I don't see any evidence in the form of other hidden files. And it won't actually create the history file unless you're using
psql interactively, which you're not.
I had this exact same problem and found this question, but the accepted answer wasn't acceptable to me -- I shouldn't have to grant postgres permission to leave a trail of my queries in whatever directory I happen to be in when I run a script!
@Corey, the solution you mentioned in your comment (
cd /tmp before calling
sudo...) is probably the best.
psql won't create this file in
/tmp (I'm sure that's deliberate, because it could allow unprivileged users to read the file).
There are two other solutions I can think of :
psql in a login shell by adding
-i to your command
sudo -i -u postgres psql < setup_dev_db.sql
This will set
HOME directory, listed in
/etc/passwd. For Ubuntu, that's
/var/lib/postgres. But since you're piping in commands, it won't create a
.psql_history file. However, if you use interactive
psql, anyone else with
sudo privileges on the machine will have access to your command history.
I'm not sure if there are any other negative consequences to running a login shell in this situation.
psql as a less-privileged user, e.g.
$ psql dev_db -hlocalhost corey_dev -W < setup_dev_db.sql
If this is a problem because you leave postgres user creation to your
setup_dev_db.sql script, and you don't have any users yet, just add a
createuser command in your script first, something like this:
$ sudo -u postgres createuser corey_dev -P
and perhaps ...
$ sudo -u postgres createdb dev_db "Dev database"
NOTE: When using the
psql client interactively (which you're not, here), if you see a message like
could not change directory to "/home/corey/scripts": Permission denied message ****,
psql is going to write to
/var/lib/postgres/.psql_history (or wherever its
$HOME is)! If you've ever seen that warning when using interactive
psql, go look--you'll probably find a hidden history file.
