PostgreSQL version: 8.2 beta
Operating system: windows xp
Description: upgrade.bat refers to msi file name for version 8.1 ms
Details:
The last line should be
msiexec /i postgresql-8.2beta2-int.msi REINSTALLMODE=vamus REINSTALL=ALL
/qr
or you can set a variable called say POSTGRES
with POSTGRES having value of the msi file name. then
msiexec just use that variable.
