I am running:
version
-----------------------------------------------------------------------------------------------------
PostgreSQL 9.4.11 on x86_64-unknown-linux-gnu, compiled by gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2, 64-bit
(1 row)
and:
pgAdmin III 1.22.2
on the same:
Description: Ubuntu 14.04.5 LTS
Release: 14.04
I can open the postgresql.conf
configuration file with pgAdmin
but not the pg_hba.conf
configuration file.
Both files are in the same directory (/etc/postgresql/9.4/main
):
-rw-r----- 1 postgres postgres 4641 Jun 10 2016 pg_hba.conf
-rw-r--r-- 1 postgres postgres 21501 Jun 10 2016 postgresql.conf
but I have noticed that the two configuration files have different permissions. I haven't modified the permissions of pg_hba.conf
to make them different from those of postgresql.conf
.
Are the permissions of these files different by default? Is there are reason why the pg_hba.conf
has more restricted read permissions? Can I go ahead and modify the permissions of pg_hba.conf
?

It's not clear what is the point in doing that, but if you're an admin you can do
chmod o+r pg_hba.conf
to let a non-admin read it.There are two ways in pgAdmin3 to access those files:
File->Open *.conf
commands. With that method, permission-wise, pgAdmin is not special, it's like a text editor or a pager.Tools->Server configuration
. This requires theadminpack
contrib module installed server-side. In the case of Ubuntu, I'm not sure it would work because the configuration files are not inside the data directory below/var
, they're under/etc/...
and the server-side functions involved are not supposed to reach anything outside the data directory. But if/when this method does work, it's thepostgres
process that reads the files, so the permissions shown in the question are good enough.
