	Return an element of a geometry collection.	Restituisce il tipo di geometria per il valore ST_Geometry.
	Return the 1-based Nth element geometry of an input geometry which is a GEOMETRYCOLLECTION, MULTIPOINT, MULTILINESTRING, MULTICURVE, MULTI)POLYGON, or POLYHEDRALSURFACE. Otherwise, returns NULL.	Restituisce la geometria numero N (a partire da 1) se la geometria è una GEOMETRYCOLLECTION, (MULTI)POINT, (MULTI)LINESTRING, MULTICURVE o (MULTI)POLYGON, POLYHEDRALSURFACE. Altrimenti restituisce il valore NULL.
	Index is 1-based as for OGC specs since version 0.8.0. Previous versions implemented this as 0-based instead.	L'indice parte da 1, come per le specifiche OGC a partire dalla versione 0.8.0. Le precedenti versioni invece implementavano un indice a partire da zero.
	To extract all elements of a geometry, <xref linkend="ST_Dump"/> is more efficient and works for atomic geometries.	Se volete estrarre tutte le geometria, <xref linkend="ST_Dump"/> è più efficiente e funziona anche nel caso di geometrie singole.
	Changed: 2.0.0 Prior versions would return NULL for singular geometries. This was changed to return the geometry for ST_GeometryN(..,1) case.

	Returns the SQL-MM type of a geometry as text.	Restituisce il tipo di geometria per il valore ST_Geometry.
	Returns the type of the geometry as a string. EG: 'ST_LineString', 'ST_Polygon','ST_MultiPolygon' etc. This function differs from GeometryType(geometry) in the case of the string and ST in front that is returned, as well as the fact that it will not indicate whether the geometry is measured.	Restituisce il tipo di geometria come stringa. P. es.: 'ST_LineString', 'ST_Polygon','ST_MultiPolygon' ecc. Questa funzione differisce da GeometryType(geometry) per il prefisso ST che viene restituito, così come per il fatto che non indica se la geometria è misurata.
	Enhanced: 2.0.0 support for Polyhedral surfaces was introduced.	Miglioramento: nella versione 2.0.0 è stato introdotto il supporto per le superfici poliedriche.

	Tests if a geometry contains a circular arc
	Returns true if a geometry or geometry collection contains a circular string	Restituisce TRUE se la geometria è una geometrycollection, un poligono o un punto vuoto, ecc.

	Returns the Nth interior ring (hole) of a Polygon.
	Returns the Nth interior ring (hole) of a POLYGON geometry as a LINESTRING. The index starts at 1. Returns NULL if the geometry is not a polygon or the index is out of range.	Restituisce una LINESTRING che rappresenta l'anello esterno per una geometria <varname>POLYGON</varname>. Restituisce NULL se la geometria non è un poligono. Non funziona con MULTIPOLYGON

	Return the number of component curves in a CompoundCurve.
	Return the number of component curves in a CompoundCurve, zero for an empty CompoundCurve, or NULL for a non-CompoundCurve input.

	Returns the Nth component curve geometry of a CompoundCurve.
	Returns the Nth component curve geometry of a CompoundCurve. The index starts at 1. Returns NULL if the geometry is not a CompoundCurve or the index is out of range.
	Tests if a LineStrings's start and end points are coincident. For a PolyhedralSurface tests if it is closed (volumetric).	Restituisce <varname>TRUE</varname> se il punto iniziale e quello finale di <varname>LINESTRING</varname> coincidono. Per le superfici poliedriche indica una superficie chiusa (volumetrica).
	Returns <varname>TRUE</varname> if the <varname>LINESTRING</varname>'s start and end points are coincident. For Polyhedral Surfaces, reports if the surface is areal (open) or volumetric (closed).	Restituisce <varname>TRUE</varname> se il punto iniziale e quello finale di <varname>LINESTRING</varname> coincidono. Per le superfici poliedriche indicase la superficie è un'area (aperta) o un volume (chiusa).

	SQL-MM defines the result of <code>ST_IsClosed(NULL)</code> to be 0, while PostGIS returns <varname>NULL</varname>.
