CTID: Anyway to lock it? - Mailing list pgsql-odbc

Hello,
I have a piece of software that uses specific record numbers in order to pull
data from PG. It uses this query:
select "votes" ,  CTID, OID from database where ctid in ('(27, 55)')'

Apparently the CTID changes per record with each update. Is there anyway to
lock the CTID so that it doesn't change everytime I update a record?

thanks,
