[Freeswitch-users] Freeswitch 1.8 : Debian package : Is postgresql still the default core-dsn ?

Hi all, I've been deploying freeswitch 1.8 package on a debian 9. When trying to connect to my own external postgres database i get this message : "2018-09-26 15:43:52.932465 [CRIT] switch_core_sqldb.c:468 Failure! PGSQL NOT AVAILABLE! Can't connect to DSN dbname BlabBlaBla.." Does this mean freeswitch 1.8 on debian 9 is built with a non postgresql core-dsn database ? Is there a way to query the core-dsn database type from freeswitch cli ? Thank for your help. J.Terrasson
