Hi,
     Does anyone have any idea what is the cause for the below error:


*** glibc detected *** postgres: ishaya mydb [local] SELECT: double free or corruption (!prev): 0x00000000026bc710 ***

I am modifying code of sorting query, but instead of the required output, this error is thrown in the logs.

Hi Ishaya,

Are you using palloc and pfree for memory management?
If not then it should be the correct way to allocate memory in postgreSQL

To debug problems like this, I usually use "valgrind".
