What is my favourite PostgreSQL GUI-admin tool? pgAdmin3. I love its light weight user interface and simple navigation. Thanks to BigSQL Development Team for surviving the tool from freeze.
With PostgreSQL release 11.0, here is my patch file corresponding catalog table changes: pgadmin3-patch-text-file
First, clone pgAdmin3 project: clone git clone https://bitbucket.org/openscg/pgadmin3-lts.git
Then, apply the patch: patch -p0 -i [patch-text-file]
Oldies but goldies.
