Re: Memory growth observed with C++ application consuming libpq.dll on Windows - Mailing list pgsql-hackers
Hi Yasir,
Are you looking for a fully functional sample program or only the APIs from libpq library that our product uses? I am asking this because if the requirement is to have a sample code, then I will have to work on creating one on the same lines as our product.

Hi Rajesh,
Can you please attach a sample code snippet showing libpq's functions being called? It will help to identify the libpq's functions to investigate further for a potential mem leak.
Regards...

Ours is a C++ application that directly loads libpq.dll and handles the queries and functions. We use setSingleRowMethod to limit the number of rows returned simultaneously to the application. We do not observe any memory increase when the application is run on Linux. There is no code difference between Windows and Linux from the application standpoint. We ran valgrind against our application on Linux and found no memory leaks. Since the same code is being used on Windows as well, we do not suspect any memory leak there. The question is if there are any known memory leaks with the version of the library we are using on Windows. Kindly let us know.The version of the library on Linux is libpq.so.5.16The windows version of the library is 16.0.3.0Thanks,Rajesh
