Hi, I'm building some custom extension on top of postgres 9.6.1. As part of that, I would like to read Heap Tuple directly from my extension using Primary Key.
By default, postgres table index(B-Tree) its PrimaryKey(PK). So, i would like to get TID by doing a lookup into PK's B-Tree index. Using which i could read HeapTuple directly. Please suggest me the easiest way to lookup into PK's B-Tree index for getting TIDs. Suggesting a postgres extensions which does B-Tree lookup will also helps me. Awaiting your response. Thanks & Best Regards - Mahi
