DSpace is trying to connect to PostgreSQL Database (the default DB) and the connection fails.
Install PostgreSQL Database first, and then try installing DSpace.

Boss!!!
You have not cleared that in which operating system you are trying to do installation of Dspace. anyway,
C:\Dspace\dspace-5.2-src-release\dspace\target\dspace-installer\build.xml:797:
ava returned: 1
refers to the failure of the testing of connection to the PGSQL database server. There are many things which lead to this type of error. most probably, either you are not installed PGSQL (PostgreSQL) Database properly or the dspace failed to connect to the PGSQL. The second one may happens due to the improper setting in the server definition or due to the proxy based IP addresses.
Whether your institution uses proxy server then just set the proxy with port in setting.xml file found in .m2 folder (which is hidden folder in the home folder in centos or Ubuntu). It may help you to solve connection problem arises due to proxy server.
Hoping that it will be useful to you.
