Trying to open "postgresql-8.0.3.zip" from 2005-05-12 with "WinZip 8.1 SR-1
(5266)" gives the following error message: ""Cannot open file: it does not
appear to be a valid archive". The file
"postgresql-8.0.3-binaries-no-installer.zip" from the same date opens OK. I
cannot remember having seen this error trying to open previous windows
installer zips. Tried to download from 3 different mirrors, but all files
gave same error, and file compare showed that the files were identical.
