Re: Upgrading

I have ever used Slackware, so no rpm's for me... gives me some control
on what to include and what not... but it learned me how to do compile
stuff ;-)

Here is what I would do:
locate all Postgresql binaries. I suppose it's in /usr/bin
dump _all_ your data (maybe stopping the postmaster and making a
filesystem backup is the most certain way to do this)
download postgres sources and 7.2.5 rpm
shutdown the postmaster
upgrade to 7.2.5 by rpm
start postmaster
dump _all_ your data if succesfull
look for any other configuration files and store them separately (there
may be something in /etc and /etc/rc.d ...)
unpack 7.4 sources
./configure --help to see all the flags you can set
./configure <all your needed flags>
if succesfull: make
if succesfull: stop postmaster
uninstall postgres 7.2.5 with rpm
make install the sources
initdb
start postmaster
restore your data
check all config files and see if they're still the same, check
/etc/rc.d startup stuff too (I honestly must say I have no idea how this
is really implemented)
enjoy!

Mind: you can also do the following starting from the ./configure part,
all that was to be done previously still applies:
stop postmaster
uninstall postgres 7.2.5 with rpm
./configure --with-all-your-flags && make && make install && initdb -D
<bladidbla>
(make will only run if configure was succesfull, make install will only
run when make was succesfull and so on)
If this is a first-timer, try this out on a non-critical system where
everything may fail! If it's not a first-timer you might still want to
do that, since one easily forgets a flag or two or makes a slight mistake.
Storing all your commands in a shell-script makes it easier to do
exactly the same stuff on another machine...

Hope it helps...
