commit da9a888da22c66764a2f97099c8f6c9462dbcbb7
Author: Fujii Masao <fujii@postgresql.org>

First released in: 18.0
doc: Clarify that total_vacuum_time excludes VACUUM FULL.
The last_vacuum and vacuum_count fields in pg_stat_all_tables already
state that they do not include VACUUM FULL. However, total_vacuum_time,
which also excludes VACUUM FULL, did not mention this. This could
mislead users into thinking VACUUM FULL time is included.
To address this, this commit updates the documentation for
pg_stat_all_tables to explicitly state that total_vacuum_time does not
count VACUUM FULL.
Back-patched to v18, where total_vacuum_time was introduced.
Additionally, this commit clarifies that n_ins_since_vacuum also
excludes VACUUM FULL. Although n_ins_since_vacuum was added in v13,
we are not back-patching this change to stable branches, as it is
a documentation improvement, not a bug fix.
