pg_upgrade project status - Mailing list pgsql-hackers

The current project is not in good shape. Feature freeze is coming and
nothing is committed. Currently there are three patches in the game:

1) Space reservation
http://archives.postgresql.org/pgsql-hackers/2008-12/msg00886.php
http://archives.postgresql.org/pgsql-hackers/2009-01/msg02031.php

This patch is mandatory for page online conversion and MUST TO be part
of postgreSQL 8.4. if not ... then we will be at the beginning next
year.

I sent updated version today.

2) pg_upgrade.sh
http://archives.postgresql.org/pgsql-hackers/2008-12/msg00248.php

Pg_upgrade.sh is shell script for catalog conversion. It works for
8.3->8.4 upgrade. It will be useful while we will not have better
solution. Disadvantage is that it is korn shell script. The idea is to
rewrite it in PERL which is more portable, but I'm not PERL expert and
currently there is no workable solution.

And what is deadline for it? We can delivery it later with 8.4.1, but
best time for testing is during betas and RC period.

3) preupgrade script
http://archives.postgresql.org/pgsql-hackers/2008-12/msg01273.php

I sent WIP version of this script, which shows how reservation space
feature will be used. This part is not important now. It will be
important for 8.4->8.5 upgrade and cannot be finished until 8.5beta.

Thats all
