Change XID and mxact limits to warn at 40M and stop at 3M.
We have edge-case bugs when assigning values in the last few dozen pages
before the wrap limit. We may introduce similar bugs in the future. At

This allows AM-specific knowledge to be applied during creation of

the latter entries the a

Hi Fujita-san
I wonder if this build farm failure is related?

Use pg_pread() and pg_pwrite() in slru.c.
This avoids lseek() system calls at every SLRU I/O, as was
