TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match

The other possibility would be to query your tables that way :

select * from "Employee_Master";

Which may not be that convenient.

Only if you have quoted the table names while creating them.

For eg, The following two commands will create tables with different names:

create table "Test"( a int );

create table "test"( a int );

create table "TesT"( a int );

Postgres converts all identifiers to lower-case, unless they are quoted.
