I just got a new mac and am getting everything installed on it (postgres, postgis, qgis, grass, gdal, brew, ruby, etc) and am about to install QGis.
QGis is a great tool for me, except for that with my other mac I was never able to get it to connect to PostgreSQL.
PGAdmin always worked when connecting, but connecting QGis to the Postgres.app implementation of Postgresql never was able to connect. The error messages were depressingly vague (just recreated):
Connection failed - Check settings and try again.
So my question is this. What are the ideal settings that allow qgis to connect easily to postgresql? I've found Postgres.app an easy to use implementation, but should I abandon it and use the normal brew-installed postgresql instead to get qgis to connect?
Or even better, is there a qgis/postgresql co-installation somewhere that would come close to guaranteeing inter-functionality between these two systems?
UPDATE: (after temporarily removing the Postgres.app PostgreSQL implementation) When I run this command:
brew install qgis --with-grass --with-postgis
brew starts off by installing postgresql. I'm going with this for now and am hoping the "pipes" between QGis & PostgreSQL will be setup to communicate with one another...
