```
Step 5: Create a New Table

To create a new table in PostgreSQL, you’ll need to use the PostgreSQL command-line tool or the SQL Server Management Studio. Here’s a step-by-step guide:

Create a new table: Use the PostgreSQL command-line tool to create a new table. For example:

CREATE TABLE <table_name> (

<column_name> <data_type>,

<column_name> <data_type>,

...

);

Create a new table in SQL Server: Use the SQL Server Management Studio to create a new table. For example:
```
CREATE TABLE <table_name> (

<column_name> <data_type>,

<column_name> <data_type>,

...

);
```

Step 6: Insert Data into the Table

To insert data into the table, you’ll need to use the PostgreSQL command-line tool or the SQL Server Management Studio. Here’s a step-by-step guide:

Insert data into the table: Use the PostgreSQL command-line tool to insert data into the table. For example:

INSERT INTO <table_name> (

<column_name> <data_type>,

<column_name> <data_type>,

...

) VALUES (

<value1>,

<value2>,

...

);

Insert data into the table in SQL Server: Use the SQL Server Management Studio to insert data into the table. For example:

INSERT INTO <table_name> (

<column_name> <data_type>,

<column_name> <data_type>,

...

) VALUES (

<value1>,

<value2>,

...

);

Step 7: Query the Table

To query the table, you’ll need to use the PostgreSQL command-line tool or the SQL Server Management Studio. Here’s a step-by-step guide:

Query the table: Use the PostgreSQL command-line tool to query the table. For example:
```
SELECT * FROM <table_name>;
```

Query the table in SQL Server: Use the SQL Server Management Studio to query the table. For example:
```
SELECT * FROM <table_name>;
```
