Sorry everybody but i just figured out what my lame butt has done wrong.
after reading the postgresql manual further i discovered the tracing
features of the db server so i decided to add this entry to pg_options
all=1
verbose=2
query=0
syslog=2
and i found this ...
Jan 10 13:02:06 darktower postgres[3891]: InitPostgres
Jan 10 13:02:06 darktower postgres[3891]: FATAL 1: Database "papers " does
not exist in the system catalog.
Jan 10 13:02:06 darktower postgres[3891]: proc_exit(0)
Jan 10 13:02:06 darktower postgres[3891]: shmem_exit(0)
Jan 10 13:02:06 darktower postgres[3891]: exit(0)
"papers " DUH! somewhere in the program a blank space had gotten
in. i fixed it and it works perfectly. Thanks to everybody that replied
to my request for help.
