error loading sf after upgrading to macOS 11 Big Sur

[franzkappa]

Hi all,

since I upgraded to macOS 11 I get this message when loading the sf library in RStudio:

> library(sf)
Error: package or namespace load failed for ‘sf’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/Library/Frameworks/R.framework/Versions/4.0/Resources/library/sf/libs/sf.so':
  dlopen(/Library/Frameworks/R.framework/Versions/4.0/Resources/library/sf/libs/sf.so, 6): Library not loaded: /usr/lib/libpq.5.dylib
  Referenced from: /Library/Frameworks/R.framework/Versions/4.0/Resources/library/sf/libs/sf.so
  Reason: image not found

I reinstalled R 4 from scratch but nothing changed. Any idea?
Thanks a lot
