Subject: Memory Usage and libpq

Message-ID: <C05813BC.27D74%hierophant@pcisys.net> (raw)
I am investigating a memory usage issue and I noticed something with libpq.
It appears that libpq doesn't actually free memory allocated to store
results, even after PQclear() is called. In a debug program I can inspect
the buffer so I know it exists. I haven't verified whether the buffer is
resized with subsequent calls, but when dealing with large result sets it
creates a significant memory overhead.
Am I on to something here or do I need to keep looking? If so, is there any
way that I can force libpq to free or in some way drastically reduce this
biffer?
Thanks,
Keary Suska
