I tried

local dbh = freeswitch.dbh("pgsql://hostaddr=127.0.0.1 dbname=some_db user=uname password='passwd'") -- returns nil

local dbh = freeswitch.dbh("odbc://some_db:uname:passwd") -- returns nil too

Also I set up ODBS with PostgreSQL driver. If I run this command in console:

isql some_db uname passwd

then I can successfully connect to my database. What am i doing wrong? Also I tried to link odbc*.ini files for freeswitch:

mkdir /usr/local/freeswitch/etc

ln -s /etc/odbcinst.ini /usr/local/freeswitch/etc/odbcinst.ini

ln -s /etc/odbc.ini /usr/local/freeswitch/etc/odbc.ini

but it doesn't help too. Thanks in advance.
