I have been experimenting with Postgres configuration parameters and noticed that when I use settings that prevent Postgres from starting nothing shows up in the pg_log directory logs. I have
log_destination = 'stderr'
logging_collector = on
log_directory = 'pg_log'
Is there a way to cause Postgres to log startup errors to pg_log on Windows 7 and Postgres 9.3?

There's a chicken-and-egg problem there.
PostgreSQL reads
postgresql.conf
to decide where to log, and how.So it cannot really log errors in
postgresql.conf
to the PostgreSQL logs, unless it uses some kind of fallback/default log.Instead, it uses the Windows Event Log, which is what Windows applications are supposed to do anyway. (You can have PostgreSQL write all logs to the Windows Event Log if you prefer, by changing its logging configuration).
So you should look in the windows event log - see the Event Viewer - for startup issues with PostgreSQL.
