Spatial axis order , srid migrations

[ArnabChatterjee20k]

• SRID fixed to 4326 for all adapters

• Axis order is long-lat for all adapters

• Mariadb doesn't support axis-order but mysql supports it and it is now default to long-lat

• In 4326 SRID, mysql uses by default [lat, long] and ST_X will give lat as x

• For geometric distances -> using srid 0 as 4326 calculates in meter

Result -> srid is fixed and we do insertion and query both in long-lat for all

Example
Long-lat insertion and fetching from mysql

INSERT INTO test_points (pointAttr)
VALUES (
ST_GeomFromText('POINT(1 2)', 4326, 'axis-order=long-lat')
);

SELECT
ST_LONGITUDE(pointAttr) AS x,
ST_LATITUDE(pointAttr) AS y
FROM test_points;
