SQL unaccent is a PostgreSQL extension that removes accents (diacritic signs) from lexemes. It is a filtering dictionary that can be used to improve user experience and implement search in a user-friendly way. The unaccent() function removes accents from a given string and can be used outside normal text search contexts. For example, SELECT unaccent('unaccent', 'Hôtel') returns 'hotel'. The unaccent extension provides a single function, unaccent(), which can be used to remove accents from words. It can even be indexed using an unaccent-based index to speed up the process.

Returns the number of mandatory arguments.
If the block is declared to take no arguments, returns 0.
If the block is known to take exactly n arguments, returns n.
If the block has optional arguments, returns -n-1
