Ah, that explains that.  Another corner case that pg_dumpall doesn't
handle :-(.

I think we are planning to eliminate usesysids entirely soon, since they
don't seem to have any real function other than creating the risk of
this sort of problem...

We try to minimize cross-version portability problems, but there are
always a few.  The release notes for 7.0 should give you more info.

Thanks for pointing me in the right direction.  I started to look at the
db.out file and I noticed the pg_shadow variables.  When I looked at the
newly built postgres 7.0.2 the usesysid for postgres was the same as the
usesysid for sys_request, one of the new accounts I was moving over.  I
fixed all of the usesysid's in the db.out file to be a few digits away from
the postgres account.  On top of that, however, I was also able to
successfully get rid of the real user accounts and add in generic accounts
that create and control each particular database.  How happy is that?  ;-)
Thanks again.


Oh, but one other question to the group...has anyone experienced any issues
when importing a database out of and older version and into a newer version?
We have several perl script which make modifications to the tables through
apache.  Are there any commands or functions that completely disappear from
the old versions or is there usually some alias built in if a command is
replaced?  We just need to make sure that we won't be losing any of the
functionality before upgrading on the production box.

Pretty bizarre.  Have you looked at the dump file to see whether the
fault is wrong output from 6.4.2, or 7.0 doing the wrong thing?

My guess is that the pg_dumpall shell script is getting confused;
it's a pretty simplistic script (particularly as far back as 6.4)
and used to have a number of bugs for off-the-beaten-track cases.
I think it may still fall over if you have a space in a database
name, for example.

[GENERAL] [General] Problems upgrading from v6.4.2 to v7.0.2

2000-07-24 Thread Fetter, David M

I'm having some issues upgrading our production postgresql, which is at
version 6.4.2, to version 7.0.2.  Here's what is happening...

I configure and make the new version of postgres (this is being done on a
separate system from the production for testing purposes).  On the
production system I do a pg_dumpall to extract all of our current running
databases.  I then ftp the outfile to the test system and perform the import
function as specific in the INSTALL file.  After doing this I have a little
dilemma right off the start.  I have two databases that are duplicated but
owned by separate users.  One database is just a production one which is
owned by postgres and the duplicate owned by the correct user as it lists on
the production system.  The other database that is duplicated is template1.
This, I think, poses more of an issue.  The first template1 db is owned by
postgres and the second is owned by the correct owner for the other
duplicated db.  Here's an example of what I'm talking about:

List of Databases
Database| Owner
-
inv | mgdotson
inventory   | rssouthw
ir  | mgdotson
lpdb| lpadmin
passwd  | mgdotson
sys_request | postgres  <--wrong, doesn't exist in
production db
sys_request | sys_request   <--correct
template1   | postgres  <--correct
template1   | sys_request   <--wrong, doesn't exist in production db
tivoli  | mgdotson

For the record the exact commands I'm using to export and import this
database are:

pg_dumpall > db.out <--on 6.4.2 production postgres
psql -d template1 -f db.out <--on 7.0.2 test postgres

Does anybody know why this is happening and more importantly how to get it
not to happen?  Also, I'm sure you may have noticed that some of the
databases are owned by regular user accounts (i.e. mgdotson and rssouthw).
How would I change the ownerships of these databases and tables to different
generic users, given that the generic users are already created?  I would
like to do this with the upgrade process as well.
