[patch] Help information for pg_dump

Hi all

After executing command [pg_dump -?], some help information is as follows.

pg_dump -?
-----------------------------------------------------------------
  -N, --exclude-schema=PATTERN do NOT dump the specified schema(s)          ※
  -T, --exclude-table=PATTERN  do NOT dump the specified table(s)           ※
  -x, --no-privileges          do not dump privileges (grant/revoke)
  --exclude-table-data=PATTERN do NOT dump data for the specified table(s)  ※
  --no-comments                do not dump comments
  --no-publications            do not dump publications
  --no-security-labels         do not dump security label assignments
  --no-subscriptions           do not dump subscriptions
  --no-synchronized-snapshots  do not use synchronized snapshots in parallel jobs
  --no-tablespaces             do not dump tablespace assignments
  --no-unlogged-table-data     do not dump unlogged table data
--------------------------------------------------------------------

I think it would be better to change [do NOT dump] to [do not dump].

Here is a patch.

Best Regards!
