Subject: postgresql 7.3
Date: Thu, 06 Mar 2003 08:53:00 -0000 [thread overview]
Message-ID: <F6E081A7-4FB0-11D7-BEEB-003065F408F0@gizmolab.com> (raw)
can you give me an approximate timeframe for redhat's release of rhdb
based on postgresql 7.3?
my problem is that I'm using redhat bugzilla 2.15 with a database
created with bugzilla based on mysql. I've managed to transfer the data
out of mysql and into postgres (no small feat), and bugzilla runs, but
it has a few bugs. I've, since then, downloaded redhat bugzilla 2.17,
only to discover that the schema expected in this version are quite
different. among the many changes, one of them can't be performed by
rhdb 2.1 (postgresql 7.2.3).
specifically: several of the tables contain essentially identical data
(eg, products.value and bugs.product) with data type varchar. this
being inefficient as a primary key and foreign key, these column
definitions are being replaced by integer primary keys and integer
references, respectively. postgres 7.3 allows the following sql:
alter table products add id int;
... set new unique values in this new id column ....
alter table products alter id set not null;
alter table products add primary key(id);
postgresql 7.2.3 doesn't allow that the "set not null" column
constraint be applied in an "alter" statement and the "add primary key"
can only be applied to columns which are designated as "not null." a
neat and frustrating shutout.
I suppose I could dump the database and reconstruct the schema
correctly, but I'd then have to seriously modify the redhat bugzilla
setup code. moral of this story? the bleeding edge is not for whimps.
