ST_Flip

ST_Flip takes a geometry column and a number and returns a geometry column. The result is the input geometry flipped around an axis using the mode specified. You can choose from the following modes:

'X_AXIS'—Flip the geometries around the horizontal axis.
'Y_AXIS'—Flip the geometries around the vertical axis.
'BOTH_AXES'—Flip the geometries around both the horizontal and vertical axes.

Function	Syntax
Python	`flip(geometry, mode)`
SQL	`ST_Flip(geometry, mode)`
