Problem: Cannot start Postgres
Platform: Postgres 8.3, Windows Vista Home
Error Message: pg_ctl: invalid data in PID file "C:/Program

I run postgres on Windows Vista Home Edition. It normally runs as a
service but is not starting. I created a command line instruction by
copying the data from Windows service GUI and changing "runservice" to
"start". Under the command line it produces the following:
C:\Users\Daron>"C:/Program Files/PostgreSQL/8.3/bin/pg_ctl.exe" start
-N "postgr
esql-8.3" -D "C:/Program Files/PostgreSQL/8.3/data" -w
pg_ctl: invalid data in PID file "C:/Program
Files/PostgreSQL/8.3/data/postmaste
r.pid"
Entering "type postmaster.pid" in the appropriate directory produces a
couple of blank lines.
I thought of trying to delete the PID file but I am not sure if it may
cause further problems.
as long as you can ensure that the server is not running, its perfectly
safe to delete the PID file.
