Formats

• %s formats the argument value as a simple 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 stringifies JSON objects, SQL-quotes small strings, dollar-quotes long strings, and emits NULLs, numbers, and booleans unquoted.
• %J stringifies the value then emits as either a SQL-string or a dollar-quoted string, depending on the length of the resulting JSON.
• %% In addition to the format specifiers described above, the special sequence %% may be used to output a literal % character.
