Comment:

 I tested this on PostGIS 2.3 running GEOS 3.6.1 and it works fine.


 {{{
 POSTGIS="2.3.2 r15302" GEOS="3.6.1-CAPI-1.10.1 r4317" PROJ="Rel. 4.9.1, 04
 March 2015" GDAL="GDAL 2.1.3, released 2017/20/01" LIBXML="2.7.8"
 LIBJSON="0.12" RASTER
 }}}



 {{{
 SELECT ST_Within(st_geomfromtext('POLYGON((61 34,66 34,66 31,61 31,61
 34))',101), st_geomfromtext('POLYGON((62 48,83 48,83 29,55 29,55 33,62
 48))',101));
 }}}

 Which version of GEOS are you running?  I suspect upgrading your GEOS
 might do the trick.

 Two reasons why we won't fix this:

 1) It's likely this is a GEOS bug, not a PostGIS bug
 2) PostGIS 1.5, we at best make only security patches on a version that
 old.
