When multiple relations are reindexed, a scan of pg_class is done first to build the list of relations to work on. However the REINDEX logic has never checked if a relation listed still exists when beginning the work on it, causing for example sudden cache lookup failures. This commit adds safeguards against dropped relations for REINDEX, similarly to VACUUM or CLUSTER where we try to open the relation, ignoring it if it is missing. A new option is added to the REINDEX routines to control if a missed relation is OK to ignore or not. An isolation test, based on REINDEX SCHEMA, is added for the concurrent and non-concurrent cases.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
