It's just convenient if you have to escape single quotes in the query string which is a common case: Detailed explanation and instructions here: The lack of key names. functions that return tables (that is, multiple rows). Also, it must not produce duplicate values, or an error In other words, we will create crosstab in PostgreSQL. Each must only include rows where the location matches the column name.
