[postgis-users] How to set right buffer

[Marcin Mionskowski]

It is working for me (POSTGIS="3.2.0 c3e3cc0" [EXTENSION] PGSQL="130"
GEOS="3.8.0-CAPI-1.13.1 " PROJ="6.3.1" GDAL="GDAL 3.0.4, released
2020/01/28" LIBXML="2.9.10" LIBJSON="0.13.1" LIBPROTOBUF="1.3.3"
WAGYU="0.5.0 (Internal)" (core procs from "3.1.1 aaf4c79" need upgrade)
RASTER (raster procs from "3.1.4 ded6c34" need upgrade)).
Try to use a projected CRS or simply remove all zeros from your example - I
belive that by default those coordinate are treated as lat/lon values, in
which case N150 can cause problems.
