Comment (by robe):

 Works on my end.  Is it possible maybe you didn't upgrade scripts during
 upgrade.  By doing


 {{{
 ALTER EXTENSION postgis UPDATE;
 }}}

 ST_MinimumBoundingCircle is an plpgsql function and I think we made recent
 updates to it, so perhaps the ones where you are having issue have out of
 date scripts.

 Given that you have various versions of GEOS all working, I would rule out
 GEOS as the culprit and even your PROJ have various flavors working, but
 ST_MinimumBoundingCircle doesn't use proj anyway.


 If you run this it will show any mismatch:


 {{{
 SELECT postgis_full_version();
 }}}

 mine reads


 {{{
 POSTGIS="2.3.3 r15473" GEOS="3.6.1-CAPI-1.10.1 r4317" PROJ="Rel. 4.9.1, 04
 March 2015" GDAL="GDAL 2.2.1, released 2017/06/23" LIBXML="2.7.8"
 LIBJSON="0.12" RASTER
 }}}



 Also output


 {{{

 SELECT postgis_liblwgeom_version();
 }}}


 mine returns:


 {{{
 2.3.3 r15473

 }}}
