* If the object id of this tuple has already been assigned, trust the * caller. There are a couple of ways this can happen. At initial db * creation, the backend program sets oids for tuples. When we define * an index, we set the oid. Finally, in the future, we may allow ...
tuple versions - one deleted by xact B and one inserted by xact A. Another reason why this would be bad is that C would see (in the row inserted by A) earlier changes by B, and it would be inconsistent for C not to see any ...
The table mytable in this case consists of one block, because the table tuples (rows) fit in one. We can look at the page header by using the page_header function together with the get_raw_page function. Mind the name of the table and the block number in the function get_raw_page...
