I am using libpq: the C application programmer's interface to PostgreSQL. 

Compile the code:

sudo cc -o testprog testprog1.o testprog2.o -L/usr/local/pgsql/lib -lpq

But i get the following error:

collect2: error: ld returned 1 exit status

And do you have at hand why the loader (ld) failed?

Package libpq was not found in the pkg-config search path.

Perhaps you should add the directory containing `libpq.pc'

to the PKG_CONFIG_PATH environment variable

No package 'libpq' found

So libpq is not in -L/usr/local/pgsql/lib ? Do you know that libpq is installed?  You may need to use the Debian package installer to get the “dev” environment 

With kindest regards, William.
