In psql you could try: \c testdb Then create the table. \conninfo will tell you which db you are connected to. Carlo On 21 Feb 2014, at 4:25 PM, Tudor Girba <tudor(a)tudorgirba.com> wrote: Yupee!

Yeah, it must be a permission/access thing. You could also try to access a system table, like select * from pg_stat_activity; On 21 Feb 2014, at 15:22, Carlo <snoobabk(a)gmail.com> wrote: > Hi > > I just tried following your steps and had the exact same issues. > What I now tried is connecting to default DB which seems to be your USER name which worked for me. > So in your scenario connect to girba as DB instead of testdb and you should succeed. > > Cheers > Carlo > > On 21 Feb 2014, at 4:16 PM, Tudor Girba <tudor(a)tudorgirba.com> wrote: > > Hi, > > > > > On Fri, Feb 21, 2014 at 7:33 AM, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > Weird, you seem to have a DB connection. > > Exactly.

Hi I just tried following your steps and had the exact same issues. What I now tried is connecting to default DB which seems to be your USER name which worked for me. So in your scenario connect to girba as DB instead of testdb and you should succeed.

Re: [Pharo-dev] Multiple-selection drag-and-drop

by Benjamin

This works: m := TreeModel new. m roots: #(1 2 3 4 5). m dragEnabled: true. m dropEnabled: true. m transferBlock: [ :p :s | TransferMorph withPassenger: s model selectedItems from: s ]. m multiSelection: true. m openWithSpec. I guess the same applies for the other model, aka, redefining the TransferMorph. I am currently working on a TransferModel to hide the morphic part of it, but it will not be in Pharo 3.0.
