It controls how <code>ORDER BY</code> handles strings, whether <code>a</code> and <code>A</code> compare as equal, and how accented characters rank relative to unaccented ones. Every text column in PostgreSQL has a collation, either inherited from the database default or set explicitly on the column or expression.</p> <p>Knowing which collations are available is useful when creating columns that need locale-specific sorting, diagnosing unexpected sort order in query results, or migrating data between databases with different locale settings.</p>
