With default access controls it still aint :(
And most of complaints I have heard are about the need of
fidgeting with pg_hba.conf to get *anything* started.
So maybe we could start with something like this at the end of initdb:
> createdb example
> psql example
sample# create table stuff(id serial primary key, data jsonb);
sample# grant all on stuff to public;
And also have the following lines in pg_hba.conf for it
local all all trust
host all all 127.0.0.1/32 trust
host all all ::1/128 trust
This would solve most of the frustration with starting pg development
for newcomers
