Hi,
I am new to postgres, can anyone provide me any links regarding where to learn about the data types and data structures of postgresql,
I am doing a project where I have to implement a new join algorithm, I know I have to make some change in the programs nodenestloop.c,nodemergejoin.c but I am not able to understand the data structures and the data types of the program.
also, does postgres implement a index based join algorithm for join algorithms in nodenestloop.c, mergejoin and hash join. if yes how ?
Thank you
