No, I do not have any hardware/memory problems and it is not damaged index.In
my forst table I can execute:
select T1.ref_field from table1 T1 where T1.ref_field = 'A1';
and it returns 10 records.
by executing
select T2.id from table2 T2 where T2.id = 'A1';
and it returns 0 rows !
Also T1.ref_field points to T2.id and T2.id is the key for T2.
Also T1.ref_field and T2.id are declared as name.

I tryed it many times and pg do not report any errors.
My version is 7.3.1 running on r.h. 7.3.
I execute :
pg_dump > myfile
Then create a new db.
And execute psql -q newdb < myfile.
