Description
I have simple linestring in srid 4326. Transforming it to srid 3857 and calling ST_OffsetCurve with distance -1 (meter) returns multilinestring with gap in the middle.
WITH sample AS (
SELECT ST_SetSRID(ST_GeomFromText('LINESTRING(18.9410244 48.4221217,18.9411421 48.4221211,18.9413075 48.4221223,18.9413848 48.4221223,18.9415133 48.4221223)'),4326) AS geom
) SELECT ST_AsText(geom), ST_AsText(ST_Transform(ST_OffsetCurve(ST_Transform(geom,3857), -1),4326)) FROM sample

I stumbled upon this bug in POSTGIS=3.3.3 PGSQL=150 GEOS=3.9.0-CAPI-1.16.2 PROJ=7.2.1 LIBXML=2.9.10 LIBJSON=0.15 LIBPROTOBUF=1.3.3 WAGYU=0.5.0 (Internal)
However, apparently it is fixed in POSTGIS=3.4.1 PGSQL=160 GEOS=3.11.1-CAPI-1.17.1 PROJ=9.1.1 LIBXML=2.9.14 LIBJSON=0.16 LIBPROTOBUF=1.4.1 WAGYU=0.5.0 (Internal)
