Ebuild of Postgres-8.3.8 almost a catastrophe

[Konstantinos Agouros]

Hi,

usually upgrade within a minor version of postgres do not need a pg_dump_all/
and reimport. But the upgrade from 8.3.7 to 8.3.8 does as the configure option
for integer-timestamps changed and thus the newly compiled server can not read
the existing database files.

Regards,

Konstantin

Thanks, dude!

This is very useful to know about.

I assume this is an upstream decision, and may be expected to apply to  
8.3.9, 8.3.10, ... also? I have no reason to "wait and see if this is  
resolved", I should be careful to do a dump and restore next time I  
upgrade?

Cheers,

Stroller.

have you opened a bug report about this? Or is there one already?

NO. It was not an upstream change. Upstream changed to integer
timestamps by default in 8.4.0, the default did not change between 8.3.7
and 8.3.8. However, in typical gentoo manner, this is configurable by
the pg-intdatetime USE flag, which is not enabled by default.

Nope didn't have the time. I needed to get the DB running again quick by:

ebuild .../postgresql-server-8.3.8.ebuild compile, interrupting this
call ./configure manually with --enable-integer-timestamps and then copying
the postgres binary in the approp. position after compiling. This is working.
The next upgrade if ~amd64 is enabled would be 8.4 so I should dump/restore
anyway. But I will do that in an appropriate timeslot.

Regards,

Konstantin
