PostgreSQL has a geometric data type of "point".  The format is listed as (x,

help docs listed a point coordinate as x= longitude and y=latitude.  Can
someone clarify what the postgres standard is?  What this will come down to
is how built-in geospatial functions will interpret the point value.

Well the point data type is just that a point with x, y coordinates. The concept of longitude and latitude are higher order defined other systems that use the point type as a building block, i.e. Postgis. So which help docs did you see the x= longitude and y=latitude statement?


Thanks - Peter
