Re: pg_restore seems slow

I did use the 'd' switch but I didn't use the 'C' switch so I'm not sure a database was actually created. Anyways, after I used the correct switches all work fast - really fast. About a 1M records per minute. I was able to peek into the server processes to see the current copy commands in effect. Would still like to see a progress indicator though :)

    I'm trying to restore my database from 8.26 into 8.3 (win32) but find
    the process to be exceedingly slow.  The database has about 60M
    records.
    I realize there will be differences based on hardware, available
    memory,
    complexity of records but when I first tried a restore with the
    verbose
    option I was able to calculate based on the index incrementing that it
    was inserting about 6500 records per minute.
    At that rate it would take 153 hours to restore my db.  I then tried
    minimizing the verbosity window and would open it only after a minute
    and the speed was improved to about 20000 records per minute.  I'm
    hoping without the verbose option that the speed increases to at least
    200000 records per minute which would be a fairly reasonable 5 hours.
    So is there any way besides using verbose to calculate the speed at
    which pg_restore is inserting records?  It would be great to have a
    'progress' option so that a person could time going out for a sail in
    the morning and then return at just the right time.  Guess you
    know what
    I'd rather be doing instead of staring at the command prompt :)

By any chance, are you using -d or -D option while doing pg_dump?
