This isn't really a question, more of a bug. As part of debugging an install on Windows 7 I installed osqa on the windows xp emulator. The installation progressed well but near the end it showed this error:
Problem running post-install step. Installation may not complete correctly Error running C:\Program Files\BitName OSQA Stack/postgresql/bin/psql -U postgres -c "CREATE ROLE bitnami LOGIN PASSWORD '...' NOSUPERUSER NOCREATEDB NOCREATEROLE VALID UNTIL 'infinity';" psql: FATAL: the database is starting up
While the install continued, I was able to run the command from DOS (with the correct password). Since the message indicates the db was starting up the install script probably needs to wait until the db is ready before sending this command.
