Description

SELECT ST_AsText(ST_GeomFromGeoHash('IamNotAGeoHash_ThisIsABug')) returns POINT(7.23566132272554 -65.0109736310277). It appears that there is no check in decode_geohash_bbox, ​https://postgis.net/docs/doxygen/2.5/dc/dc0/lwalgorithm_8c_source.html#l00584, for characters that are not defined in base32.
