If P is not a polygon, geopoly_bbox(P) returns NULL.

<p>
The geopoly_group_bbox(P) function is an aggregate version of geopoly_bbox(P).
The geopoly_group_bbox(P) function returns the smallest rectangle that will
enclose all P values seen during aggregation.

<h2>The geopoly_contains_point(P,X,Y) Function</h2>

<p>
If P is a polygon, then geopoly_contains_point(P,X,Y) returns a 
non-zero integer if and only
if the coordinate X,Y is inside or on the boundary of the polygon P.
If P is not a polygon, geopoly_contains_point(P,X,Y) returns NULL.

<p>
The VACUUM INTO command is transactional in the sense that
the generated output database is a consistent snapshot of the
orgininal database.  However, if the VACUUM INTO command is
interrupted by a unplanned shutdown or power lose, then
the generated output database might be incomplete and corrupt.
Also, SQLite does not invoke fsync() or FlushFileBuffers()
on the generated database to ensure that it has reached
non-volatile storage before completing.

    in SQLite 3.24.0 ([dateof:3.24.0]) and earlier.)^  More specifically,
    when this flag is on
    the [ALTER TABLE RENAME] command only rewrites the initial occurrence

    <li> References to the table within the bodies of triggers and views.
    <li> References to the table within CHECK constraints in the original
         CREATE TABLE statement.
    <li> References to the table within the WHERE clauses of [partial indexes].
