BUG #4860: Indexes gone after restore

The following bug has been logged online:

Bug reference:      4860
Logged by:          Regina

PostgreSQL version: 8.4rc1
Operating system:   Windows
Description:        Indexes gone after restore
Details:

This I think is an issue with prior versions as well, but was hoping it
would have been changed in this.

I'm not sure this is considered a bug, but it is annoying.  I dumped a 8.2
using pg_dump 8.4 and restored using pg_restore 8.4. Using 8.2 makes no
difference.

If I have a functional index in place in a table in non-public schema that
uses a function in public schema, these indexes never get restored.

Something like

CREATE INDEX idx_the_geom_2249_parceltime_2008
  ON assessing.parceltime_2008
  USING gist
  (st_transform(the_geom, 2249))
  WHERE the_geom IS NOT NULL;

I always have to manually recreate these.

I think someone else on PostGIS group complained about this a while ago.  I
think its because of the SET SCHEMA in the restore.
