Yes. Also a VACUUM. Also forcing a REINDEX on the major involved tables.
Also running counts on the pg_* system tables to see if any objects did not
get restored from the backup as compared with the live database.
By everything I can measure, the live database and the test are identical; yet
the test does not think that idx_caseclients_case is very accessable, and the
live database knows it is.
Is this perhaps a bug with ANALYZE statistics in 7.2.4? I know that in that
version I don't have the option of increasing the statistics sampling ...
