BUG #11221: pg_restore unusable for expensive matviews

The following bug has been logged on the website:

Bug reference: 11221
Logged by: Jiri Baum

PostgreSQL version: 9.3.5
Operating system: Linux
Description:

When restoring a database with expensive materialized views, pg_restore
issues the REFRESH MATERIALIZED VIEW commands without regard to whether
indexes are valid yet or whether autoanalyze has completed.

As a result, if a materialized view is expensive and relies on indexes
and/or good query plans, the restore will take prohibitively long.

This is likely to be a common use case, since there's not much point
materializing views that are inexpensive.

Possible solution: pg_restore should have an option (default?) to wait for
indexes to be valid and run ANALYZE before issuing the REFRESH MATERIALIZED
VIEW commands, either in pg_restore itself or by adding commands to wait for
(relevant or all) indexes to be valid.

Workaround: Hack stuff up out of the -l and -L options to pg_restore.
