How to read the bearing angle in postgis ST_Azimuth (geometry)

Question

I have calculated the bearing of two sets of points using the ST_Azimuth (geometry) function of Postgis.

I get values like

1.42985896479537 1.44293722688266 1.45994672393791 1.48436591051383 1.51617271196433 4.22987568535437 4.27561945155804

can anyone tell me how to make sense of them. I am trying to locate points which are on right and which are on left side of other point set.

Answer 1

Use like this:

select
   degrees(st_azimuth(geom,geom)) as your_column
   from
   your_table;
