 When there is no connection set using `db.connect` or authentication using
 `db.login`, `v.out.ogr` does not say what's wrong. Instead a misleading
 (?) error about database creation is shown:

 {{{
 $ v.out.ogr in=lakes at PERMANENT output=PG:dbname=gis format=PostgreSQL
 type=area
 ERROR 1: PQconnectdb failed.
 could not connect to server: No such file or directory
         Is the server running locally and accepting
         connections on Unix domain socket
 "/var/run/postgresql/.s.PGSQL.5432"?

 ERROR 1: PostgreSQL driver doesn't currently support database creation.
 Please create database with the `createdb' command.
 ERROR: Unable to open OGR data source 'PG:dbname=gis'
 }}}

 Executing `db.connect` and `db.login` actually does not solve the problem
 for me: `db.tables -p` lists tables but `v.out.ogr` still says the same. I
 suppose this might be my problem, I might have misinterpreted the manual,
 but in any case the initial message is wrong.

 The special thing about my environment is that I'm using PostgreSQL
 database in a Docker container from
 [https://registry.hub.docker.com/u/kartoza/postgis/ kartoza/postgis]. I
 used their steps to run it and `psql` works for me (in GRASS session):

 {{{
 psql -h localhost -U docker -p 25432 -l
 }}}
