hi everyone

i am using PostgreSQL 7.3.2 on linux machine(Red Hat 3.4.3-9.EL4).

when am i executing a following query to database
select * from Table_Name;
it gives a message
" message type 0x44 arrived from server while idle
this probably means the server terminated abnormally
before or while processing the request
the connection to the server was lost :attempting reset :failed "

and also when i am copying data from table to a text file,it give 75,000 rows(Count(*) of Table_Name is 1,30,000).

Please suggest me what's the reason behind this.
