Thank you everybody, for all the suggestions. I'm using postgres 8.2 and with with that driver I can upgrade to 9.2 basically without changes on the software, this is the only reason why I'm looking for that driver. I've understand from your answers the postgresql 9.2 is also an old unsupported release, so I think it's better to upgrade to some new driver. I'm working on Delphi 7, what driver you suggest to use ? Kind Regards -- Sent from: http://www.postgresql-archive.org/PostgreSQL-general-f1843780.html
