thanks for all of the input everyone. I believe you have helped lead me to the
problem. two days ago iI ran out of room on the partition. Postgres was
running at the time, but complaining about the fact that it was out of room.
so in an effort to make more room I foolishly removed what I thought was a test
db. that was where postgres looks for its configuration info. when postgres
died today it wasn't able to find that info for the restart. If it wouldn't
have died for whatever reason today it would never have needed to locate those
files. I guess it's time to reload postgres. Any suggestions aout how?
thanks again
