Hi,

Can you please tel me the location in code where I can allocate space
before begin transaction call?

Right now, I am using spi_palloc function to alloctae memory to my
structure instance. I want to insert 10 rows in a table and want to store
the corresponding transaction ID in one link list. But, I am not able to
store them in a link list I alway loose the previous information and hence
cannot traverse the linklist to store new transaction Id at the end of link
list

Some senior in my course said, I am using wrong memory context. Can anyone
explain me the actual problem?

I have defined my struct in a header file and trying to create a simple
link list in one .c file.
