/*-------------------------------------------------------------------------
*
* pg_restore.c
* pg_restore is an utility extracting postgres database definitions
* from a backup archive created by pg_dump using the archiver
* interface.
*
* pg_restore will read the backup archive and
* dump out a script that reproduces
* the schema of the database in terms of
* user-defined types
* user-defined functions
* tables
* indexes
* aggregates
* operators
* ACL - grant/revoke
*
* the output script is SQL that is understood by PostgreSQL
*
* Basic process in a restore operation is:
*
* Open the Archive and read the TOC.
* Set flags in TOC entries, and *maybe* reorder them.
* Generate script to stdout
* Exit
*
