After this error happens, I can not access database at all.

Hmm.  Who knows which one of the data-corrupting unfixed known bugs in
this ancient version caused this particular problem.  I doubt you will
find much people trying to figure it out; instead, you should be looking
into doing an upgrade rather soonish.

Thak you for your quick reply.

Is this  the 'unfixed know bugs' of 7.2.X ? It means the solution
is only upgrading PotgreSQL to 7.3.X ot 7.4.X ?

One more information.  I have rebooted the system after this trouble
happens,
I was able to access database normally and error log messsage never
generated.
But I have not tried to run SQL command 'INSERT INTO SDBA2 SELECT * FROM
VHIST2';
since this is the production environment our clients are using now...
