sure I did, I created that new table on the database, while the
database was in use by different users. Usually I am not doing this,
but migration writes its own book, sometimes :-)

So, even if none of the existing connections can be using that table,
after a metadata change I should expect this or similar problem before
disconnecting all and probably do a backup/restore?

I'll keep that in mind, hopefully it won't happen too often :-)


Thanks,
