Hey Vladimir,



2010/9/24 Polyakov Vladimir <vvpolyakov@gmail.com>
Program written in C using Libpq, which receives large files (BYTEA)
has a memory leak.
I need to free ALL of the used memory after each sql query.

after each call PQclear() I drop the buffer:
   conn->inBuffer = realloc(conn->inBuffer, 8192);
   conn->inBufSize = 8192;

It works, but ..
I noticed that in some cases PQclear() does not clear the memory.
This happens only when the program receives certain files...

Why do you need realloc() after PQclear()?
