Hi All,
Can any one tell me, how refrential integrity is maintained
internally in postgresql. This will help in design my database
accordingly. I have the doubt that reference to a column in a table
means a pointer to the referenced column. So that even the value is
repeated several times in the side table, that will only be referencing
the main table or all the datas are maintained separately in the side
table. What mechanism has been followed to maintain the integrity.
Can any one help me.
