PostgreSQLand asterisk

Hi. I have tried isntalling odbc,postgreSQL and asterisk from scratch. I have installed odbc correctly and postgresql and asterisk correctly(I guess) I did not get some errors during installation. after installing asterisk, I started it using asterisk -p. I tried to do some query like odbc show. I got some errors since i haven’t configure the drivers yet. All modules are running. My problems is that when I started to configure my odbc driver, res_odbc_conf, my postgresql database problems also arised. When I started asterisk with “asterisk -p” the system hangsup. I tried starting again my syste and issue a asterisk -vvgc it hangs on certain part. Here is the output after issuing a “asterisk -vvgc”

I dont know what is wrong with this one. Please help me on my problem thanks. By the ways here is some part of my configuration files
