Hi Team,

I am trying to test a code which basically tries to read some data from postgresql db in a loop through a function SQL_get_tpf_rw() whose definition and other details are shared in the attached file along with the memory leak report resulted during testing. Could you let me know if i missed calling  anywhere PQclear()

in SQL_get_tpf_rw() which resulted in the below .

Last few lines from the report

yep:  for example,

      if (PQresultStatus(res) != PGRES_TUPLES_OK)           {                LOG_ERROR("SELECT failed: %s", PQerrorMessage(conn));		LOG_DEBUG("ROLLBACK TRANSACTION AND CHAIN");		res = PQexec(conn,"ROLLBACK TRANSACTION AND CHAIN");		LOG_ERROR("INVALID_FILE_ADDRESS %08X",fa);		rc = ERR_INVALID_FILE_ADDRESS;

See highlighted bits.  You're reusing the res object before clearing it.  there may be other cases, but this jumped off the page.
