Quote issue to preserve the case of the column name

[SOHELAHMED7]

In PgSQL, if a table is created with camel case (or other way in which case of all chars is not same) column name e.g. firstName without the quotes then it is case insensitive and is converted to e.g. firstname

In order to make it case-sensitive, column name should be quoted "firstName" everywhere it is used.

However this is not same in MySQL.

-- Mysql will say error: #1060 - Duplicate column name 'firstname'

CREATE TABLE `tmp_table_2_` (
	`firstName` varchar(255) NOT NULL,
    `firstname` varchar(255) NOT NULL
)

-- Pgsql will run this successfully

CREATE TABLE `tmp_table_2_` (
	"firstName" varchar(255) NOT NULL,
    "firstname" varchar(255) NOT NULL
)
