Formats

• %s formats the argument value as a simple string. A null value is treated as an empty string.
• %Q formats the argument value as a dollar quoted string. A null value is treated as an empty string.
• %I treats the argument value as an SQL identifier, double-quoting it if necessary. It is an error for the value to be null.
• %L quotes the argument value as an SQL literal. A null value is displayed as the string NULL, without quotes.
• %% In addition to the format specifiers described above, the special sequence %% may be used to output a literal % character.
