    Description

      For some functions there are ST_ synonyms, while for others (of the same kind) there are none. It makes SQL incompatible with e.g. PostGIS.

      Example:

      MariaDB [test]> select PolygonFromText();
      		 
      ERROR 1582 (42000): Incorrect parameter count in the call to native function 'PolygonFromText'
      		 
      MariaDB [test]> select MultiPolygonFromText();
      		 
      ERROR 1582 (42000): Incorrect parameter count in the call to native function 'MultiPolygonFromText'
      		 
      MariaDB [test]> select ST_PolygonFromText();
      		 
      ERROR 1582 (42000): Incorrect parameter count in the call to native function 'ST_PolygonFromText'
      		 
      MariaDB [test]> select ST_MultiPolygonFromText();
      		 
      ERROR 1305 (42000): FUNCTION test.ST_MultiPolygonFromText does not exist

      So, there are both PolygonFromText and ST_PolygonFromText, but only MultiPolygonFromText, no ST_MultiPolygonFromText.

      There might be other ones missing as well.

            There is also ST_Relate() only, not Relate(). Some of these functions are documented as behaving differently in the KB. For example, Within() is documented differently to ST_Within(). If this is correct, it's going to be very confusing to have some functions as synonyms, and others implemented differently.
