Add PROCESS_MAIN to VACUUM
Disabling this option is useful to run VACUUM (with or without FULL) on
only the toast table of a relation, bypassing the main relation. This
option is enabled by default.
Running directly VACUUM on a toast table was already possible without
this feature, by using the
Improve the regression tests of VACUUM (PROCESS_TOAST)
All the regression tests of VACUUM (PROCESS_TOAST) were only checking if
the commands were able to run, without checking if VACUUM was really
running on what it should. This expands this set of tests so as we now
look at

Revise pg_pwrite_zeros()
The following changes are made to pg_write_zeros(), the API able to
write series of zeros using vectored I/O:
- Add of an "offset" parameter, to write the size from this position
(the 'p' of "pwrite" seems to mean position, though POSIX does not
outline ythat directly),

SQL JSON path enhanced numeric literals
Add support for non-decimal integer literals and underscores in
numeric literals to SQL JSON path language. This follows the rules of
ECMAScript, as referred to by the SQL standard.
