To correctly escape characters in a command-line PostgreSQL query, you can use the backslash () character to escape special characters such as quotes and semicolons. Here are some examples:

  1. To escape a single quote ('):
1
SELECT * FROM table WHERE column = 'It''s a test';


  1. To escape a double quote ("):
1
SELECT * FROM table WHERE column = 'This is "quoted"';


  1. To escape a semicolon (;):
1
SELECT * FROM table WHERE column = 'This is a ; test';


  1. To escape a backslash ():
1
SELECT * FROM table WHERE column = 'This is a backslash \ test';


By using the backslash character to escape special characters, you can ensure that your PostgreSQL query is correctly interpreted by the command-line interface.
