Comment (by robe):

 I think our check for guc


 {{{
 const char *guc_installed = GetConfigOption(guc_name, TRUE, FALSE);
 }}}

  is flawed.

 The issue AFAICS is when I do:


 {{{
 set postgis.backend = 'sfcgal';
 }}}


 It registers that guc is installed, but my postgis library hasn't actually
 loaded yet.

 So what happens is it doesn't use the one I set and ends up using the
 default postgis.backend='geos' one (the default when no guc is set).


 I have to remark out both these lines:


 {{{
  elog(WARNING, "'%s' is currently set to '%s' and cannot be changed until
 you reconnect", guc_name, guc_installed);
  return;
 }}}

 to get it to work, otherwise sfcgal backend does not kick in.
