At the end of regression normal test, the following message
is displayed.

"To run the optional huge test(s) too type 'make bigtest'"

Many users, especialy those who install "PostgreSQL" for the
first time, may type 'make bigtest' and may feel the PostgreSQL
unstable. Because the bigtest outputs no messages for long time
and seems to be no executing at the point of numeric testing.

Therefore, if it is not necessary for the general user to
execute "regression bigtest", I think that the message of
'make bigtest' should be removed or that the message should be
changed like "it takes several hours ....".

I think so too.
