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.
