No ideas here ...

Can you please find out the current Xid counter?  I think pg_controldata
should tell you.

Also, can you restore the previous state of pg_database, the one before
you deleted the old tuple?  If not, maybe a pg_filedump of the table
file (in the hope that it hasn't been vacuumed) could show something
enlightening.

A sequence that reproduces it would be the best thing ...

I guess the trick is, I have no idea what's happened or what I did to 
cause it to happen... Any ideas I can try?

So the "nexxia" row did get updated at some point, and either that

Nope.

Beyond the occasional ALTER COLUMN (few and always completed), the only 
thing I do directly in the shell are pretty standard queries while 
working out my program. Even then, the database is dropped and recreated 
fairly regularly with backup copies from the server.

I guess this is an old release, and you haven't been vacuuming
pg_database regularly, yes?

Hi all,

template1=# DROP DATABASE nexxia ;
ERROR:  database "nexxia" does not exist

  So I still have a phantom DB there. This is still true after stopping 
and restarting the daemon, too. When I try to connect to the database I 
get this:


template1=# \c nexxia
FATAL:  database "nexxia" does not exist
Previous connection kept

  Does this mean a connection is still open somewhere? If so, how did it 
survive the daemon restarting? More specifically, how do I clear it?


Thanks!
