I'm using OSX 10.6 and just downloaded and installed
PostgreSQL 9.0.2-1 and
pgRouting 1.0.5-1 for Postgres 9.0 from here.
I'm a confused what my next steps are though. I'd like to try loading a simple network into pgRouting and running a few different network routing analyses on it to test it out. However, I don't know where to begin.
How do I open PostgreSQL or pgRouting? I'm fairly comfortable with terminal commands and scripting, but as I installed precompiled versions, I don't know where anything is or what to get at. I have looked at the pgRouting documentation, but I didn't see anything similar to my question.
