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,

For Peter's purposes, it's unnecessary to worry about anything older
than 6.4, since he's depending on an up-to-date libpq and current libpq
won't talk to anything older than 6.4.

Byron might still care about 6.2 ... I dunno whether ODBC currently
really works with 6.2 or not, or whether it needs to keep doing so.

It still really works with 6.2!   But whether it needs to, is another
question!

I'm not sure if anyone cares if it works with 6.2 (even 6.3 for that
matter) or not.
