Re: Add 64-bit XIDs into PostgreSQL 15

Thanks, done!

Also add copying of the xmin and xmax while page is locked. In heapgetpage we have to copy tuples xmin and xmax while

we're holding a lock. Since we do not hold a lock after that, values of xmin or xmax may be changed, and we may get

incorrect values of those fields. This affects only the scenario when the user select xmin or xmax "directly" by SQL query, AFAICS.
