Hello everybody!

Consider this (psql of 6.4, on i386-Linux 2.02b7):

   db=> begin work;
   db=> create table xxx (xx smallint);
   db=> insert into xxx values (1);
   INSERT 136937 1
   db=> rollback;

The following is interesting:

   db=> select * from xxx;
   ERROR:  xxx: Table does not exist.
   db=> create table xxx (xx smallint);
   ERROR:  xxx relation already exists

Hmmm. And then:

   db=> drop table xxx;
   ERROR:  Relation xxx Does Not Exist!                         
   db=> \dt
   NOTICE:  (transaction aborted): queries ignored until END
   Couldn't find any tables!                 

After quitting and re-entering psql it is possible again to create a
table "xxx". Seems to be a little bug, or did I overlook something?

BTW, is ist possible to get "nested" transactions (e.g., to realize a
multilevel "undo" in data entry forms)?
