MATLAB: Connecting PostgreSQL with MATLAb using mex wrapper

postgresql matlab mex

I am trying to use a mex wrapper to connect the Matlab with PostgreSQL.
I have found the program at http://www.shivakar.com/programming/creating-matlab-mex-function-for-postgresql-database-connectivity/
I am getting following error while compiling it on MATLAB
>> mex -DWindows -IC:\PostgreSQL\pgsql\include -LC:\PostgreSQL\pgsql\lib -lpq libpqmex.c 
Writing library for libpqmex.mexw32

    C:\PROGRA~1\MATLAB\R2011A\BIN\MEX.PL: Error: Link of 'libpqmex.mexw32' failed.
Please help me.
Thanks in advance

I was able to compile the program successfully using the following:
   mex testfunction.c -IC:\MatlabWork\Answers\pgsql\include 
-LC:\MatlabWork\Answers\pgsql\lib -lpq
Are you using a C++ compiler? That might be the issue here?
