Thanks for the help Franklin, I downgraded PgAdmin to the 1.18 ver. x64 amd. The problem is still here :(
This issue had already been reported in the mailing list and left unresolved, see : http://www.postgresql.org/message-id/canmabuitofkfzsaf-dnzfr+_c1lb9cleen+mvznucslcvyi...@mail.gmail.com So now, I don't know whether It is related to my issue or not, I also observed that errors were raised during the PGADMIN 1.18 installation. It seems linked to pg-admin3 data dependency, although It does not prevent PgAdmin from being installed and started on my computer. I have put the install. log at the bottom of this message. I have also tried to completely remove PgAdmin3 from my computer. Here's what I've done : sudo apt-get purge --auto-remove pgadmin3 sudo apt-get purge pgadmin3 (Obviously It does not totally remove PgAdmin, because the servers configured in PgAdmin are still found when PgAdmin is then re-installed...) I have also tried to compile my own version of PgAdmin from the source, but I lack skills to complete the process which involves other knowledges... I don't know what else to do ! I'll stick to using PgAdmin in a Virtual Machine, which is not a satisfying solution ! ~/Downloads$ sudo dpkg -i pgadmin3_1.18.1-2_amd64.deb [sudo] password for gallien: (Reading database ... 419835 files and directories currently installed.)
