Hi, I installed postgres from http://www.postgresql.org/ . I have version
94 and 95 installed and running on my windows 7 machine in 64 bit. I use
pgAdmin and these installs are running with no problems. I get the
aforementioned error message when I execute: "
CREATE EXTENSION plpython3u
SCHEMA pg_catalog
VERSION "1.0";'

Also when I try "CREATE PROCEDURAL LANGUAGE 'plpython3u', same
result.Dependency walker shows a dependency on PYTHON33.DLL and there is no
such file as that either in /lib or /bin. So, according to various
"solution", I should be able to download this missing DLL . I've not done
this yet because 1) it seems suspicious that a DLL is missing from the
install and 2) I don't tend to trust sites that offer free DLLs. Virus
city.
