It appears, just from a spot check of the initial database structure
created from old RPMS on rpmfind.net that pg_description was added
after 6.2 whose "provides" looks like this (for 6.2.1):

...
/var/lib/postgresql/data/base/template1/pg_attrdefind
/var/lib/postgresql/data/base/template1/pg_attrelidind
/var/lib/postgresql/data/base/template1/pg_attribute
/var/lib/postgresql/data/base/template1/pg_class
/var/lib/postgresql/data/base/template1/pg_classnameind
/var/lib/postgresql/data/base/template1/pg_classoidind
/var/lib/postgresql/data/base/template1/pg_index
/var/lib/postgresql/data/base/template1/pg_inheritproc
/var/lib/postgresql/data/base/template1/pg_inherits
/var/lib/postgresql/data/base/template1/pg_internal.init
...

while for 6.3.1, the initial database structure looks like:

...
/var/lib/pgsql/base/template1/pg_class
/var/lib/pgsql/base/template1/pg_class_oid_index
/var/lib/pgsql/base/template1/pg_class_relname_index
/var/lib/pgsql/base/template1/pg_description
/var/lib/pgsql/base/template1/pg_description_objoid_index
/var/lib/pgsql/base/template1/pg_index
/var/lib/pgsql/base/template1/pg_inheritproc
...

And of course, it appears also in 6.4.x, so I assume that it was added
between the 6.2 and 6.3 releases. Is that going to be a problem?

Hope that helps,
