Thats what i feared from the begining. (some connection between the data dir
and the executable, really, why does the executable need to be exactly the
same,
if we are talking about minor postgresql upgrade 7.4.12->7.4.13?)
The old system is kind of old, and there would be libraries
incompatibilities if a was to retain the old executable.
So i'll do it the formal way, and pray lotus notes will behave :)
