It is related to windows unquoted service path vulnerability in the the installer that creates service path without quotes that make service.exe to look for undesirable path for executable.

postgresql-9.3 service path : C:/Users/asif/Desktop/Program files/9.3/bin/pg_ctl.exe runservice -N "postgresql-9.3" -D "C:/Users/asif/Desktop/Program files/9.3/data" -w

service.exe

Fix :

postgresql-9.3 service path : "C:/Users/asif/Desktop/Program files/9.3/bin/pg_ctl.exe" runservice -N "postgresql-9.3" -D "C:/Users/asif/Desktop/Program files/9.3/data" -w

It would be good if this is reported on pg installer forum or security forum. Thanks.
