Description
What steps will reproduce the problem?
- SELECT
ST_GeomFromText(ST_AsText(ST_Buffer(ST_GeomFromText('LINESTRING(-116.93414544665981 34.16033385105459,-116.87777514700957 34.10831080544884,-116.86972224705954 34.086748622072776,-116.9327074288116 34.08458099517253,-117.00216369088065 34.130329331330216,-117.00216369088065 34.130329331330216)', 4326), 0)))
What is the expected output? It should return some hex binary since the buffer returns a POLYGON EMPTY
What do you see instead? a) On 1.3.5 (GEOS 3.0.3 )— gives error ERROR: parse error - invalid geometry CONTEXT: SQL function 'st_geomfromtext' statement 1
b) On POSTGIS='1.4.0SVN' GEOS='3.1.0-CAPI-1.5.0' PROJ='Rel. 4.6.0, 21 Dec 2007' USE_STATS
gives error ERROR: parse error - invalid geometry HINT: 'POLYGON( EMPTY' ←- parse error at position 14 within geometry
Note that:
SELECT ST_AsText(ST_Buffer(ST_GeomFromText('LINESTRING(-116.93414544665981 34.16033385105459,-116.87777514700957 34.10831080544884,-116.86972224705954 34.086748622072776,-116.9327074288116 34.08458099517253,-117.00216369088065 34.130329331330216,-117.00216369088065 34.130329331330216)', 4326), 0))
Yields: POLYGON( EMPTY) (whats that space after the first paren for? thought getting rid of the space doesn't help)
however:
SELECT ST_GeomFromText('POLYGON EMPTY') works fine.
