[Dmitry Baryshnikov]

Hi Sarthak,

1. The GDAL have 2 postgis drivers (raster and vector).
2. You need to add some information to the doxygen comment of 
GetConnectionInfo method about new functionality.
3. Do you look at psql behaviour? It seems to me the ticket author means 
to get the database name not only from environment variable, but also 
from the current logged user name.
4. There is a logic error: You form connection string based on 
parameters (papszParams) here - 
https://github.com/sarthak-0415/gdal/blob/trunk/gdal/frmts/postgisraster/postgisrasterdataset.cpp#L2502 
, but change the
papszParams below (i.e. 
https://github.com/sarthak-0415/gdal/blob/trunk/gdal/frmts/postgisraster/postgisrasterdataset.cpp#L2605). 
Also changed papszParams never used and only freed here - 
https://github.com/sarthak-0415/gdal/blob/trunk/gdal/frmts/postgisraster/postgisrasterdataset.cpp#L2735. 


Best regards,
     Dmitry
