Any Gentoo users interested in a slotted PostgreSQL

[Jyry Kuukkanen]

Hello

Are there any Gentoo users here?

Yes, there are some :)

Do you wish the PostgreSQL ebuild made use of SLOTS?
- to allow installing of major versions together (eg. 7.3 and 7.4 on the
same host)
- to ease migration of databases to new major versions (where a
dump/reload is required)
http://bugs.gentoo.org/show_bug.cgi?id=42894
With a initial plan for relocation of files to support slotting.
Comments, suggestions, corrections, or messages to say it's a silly idea
(and why)
would be very much appreciated before I attempt this next week.

I only have Gentoo installed on my old laptop that is not in very heavy
and active use. However, PostgreSQL is installed on it and used every now
and then.

PostgreSQL migration has always worked fine for me, so it has been
adequate to install fresher version on some sundry hardware and test the
migration with it.

This, quite obviously, is only my humble opinion and based on my limited
experience :)

Cheers,

After using Slackware for my production servers for years, I decided to try out
Gentoo. Since it was so easy to download and install, I decided to try to use
the PostgreSQL Ebuild. I just didn't like how and where it installed the
software, so I removed it to go with a src tarball. I'm no Portage expert, so
I'm not exactly sure if it would be possible to tweak the install to something
I'm more comfortable with. Also, migration was a BIG issue for me. I ALWAYS run
new versions parallel to old versions for testing and "the Big Move".

I'd like to see what sort of thing the Portage gurus can do with multiple
slotted installs of PostgreSQL. But, I'll be cautious for certain. I'll
probably always lean toward managing my own PostgreSQL upgrades.

I'll keep an eye on that thread that you started...

I've submitted a slotted ebuild for testing at:
http://bugs.gentoo.org/show_bug.cgi?id=42894

It's the first slotted ebuild i've attempted, so it may be total rubish!
But I have managed to get 7.3.5 and 7.4.1 installed and running in parallel
(see attachment notes on bugs.gentoo.org).
