Help needed for the resolution of memory leak

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
