Internallyit functions by querying the database for a list of tables which are appropriate given the command line
switches,and then calls amcheck's functions to validate each table and/or index.  The options for selecting/excluding
tablesand schemas is patterned on pg_dump, on the assumption that interface is already familiar to users.

The tool doesn't hold a single snapshot or transaction for the lifetime of checking the entire database.  A future
improvementto the tool might add parallelism.  Users could do all of this in scripts, but having a single tool with the
mostcommonly useful options avoids duplication of effort.
