Hi:
I have heard that Heap-Only Tuples is introduce from 8.3.
And I am searching information for it.
How can I get a detailed information of HOT?
http://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/backend/access/heap/README.HOT;hb=HEAD
For example:
according to a table, How many tuples are heap only tuples , and how
many are not?
And also , Is there any options which can influence HOT occurrance?
Best Regards
