How to edit `postgresql.conf` with pgAdmin 3? How does one edit the 'postgresql.conf' file with the pgAdmin app?

With pgAdmin 1.18.1 on Postgres 9.3.x, when I choose File > Open postgresql.conf I get a file picker dialog. And, yes, I'm connected in pgAdmin as the superuser 'postgres'.

To edit the postgresql.conf file:Choose Tools > Server Configuration > postgresql.conf
To edit the pg_hba.conf file:Choose Tools > Server Configuration > pg_hba.conf


Avoid the red-herring File menu:


File > Open postgresql.conf
File > Open pg_hba.conf
