New version of PL/Proxy is out.
Main change is that default remote username is now taken from current_user, not
session_user. Also internal connection cache now supports having connections
to same cluster under different usernames. Both changes together make
SECURITY DEFINER functions work sensibly.
Old behaviour was targeted to support obscure security schemes
for connect strings, but this is now obsoleted by SQL/MED.
PL/Proxy is database partitioning system implemented as PL language.
