Tom,
The extent of the messages I received from the command
pg_dump -Fc --table=casedocument -d tigrissave | pg_restore --verbose -d
tigris is listed below:
pg_dump: SQL command failed
pg_dump: Error message from server: server closed the connection
unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
pg_dump: The command was: FETCH 100 FROM _pg_dump_cursor
pg_restore: [custom archiver] could not read data block -- expected 1,
got 0
pg_restore: *** aborted because of error
I had removed all the files in pg_log prior to getting this error and no
new logfile was created. I'm guessing I screwed up the logger when
removing all the files, but I assumed that when writing to the error
logs the backend would create a file if one did not exist.
I currently attempt to run the dump/restore with the zero_damaged_pages
turned on to see if the results yield something more useful.
About the beta version, this is temporary, hadn't really planned on
running production on our development box. Haven't had any issues with
8.1beta for a few months and will be moving to 8.1.x as soon as some new
hardware arrives (about a week).
thanks
