Trying to convert unix time to date time format, I encountered a database crash. Environment : WINDOWS 7 Professional - Service Pack1 -- -- PostgreSQL 8.4.7, compiled by Visual C++ build 1400, 32-bit -- SELECT to_timestamp(1306760400); 2011-05-30 15:00:00+02 -- -- PostgreSQL 9.1beta1, compiled by Visual C++ build 1500, 32-bit -- SELECT to_timestamp(1306760400); ********** Errore ********** -- SELECT version(); ********** Errore ********** no connection to the server -- Trying to re-click on the connection in the pgAdminIII server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.
