Inheritance in postgre means you will have same fields definition
like the inherited table plus its own fields. So if table B is inherit
table A,
table B will have same field definition like A plus table B own
unique field(s).
It wont share primary keys, table B just have primary key in the same
field(s) like A
and records in table A wont be replaced by record(s) inserted to table B
or vice versa.
table A and table B basically a different entity, they just have same
fields definition.
Hope that will help you
