3 : * pg_restore.c
4 : * pg_restore is an utility extracting postgres database definitions
5 : * from a backup archive created by pg_dump using the archiver
6 : * interface.
7 : *
8 : * pg_restore will read the backup archive and
9 : * dump out a script that reproduces
10 : * the schema of the database in terms of
11 : * user-defined types
12 : * user-defined functions
13 : * tables
14 : * indexes
15 : * aggregates
16 : * operators
17 : * ACL - grant/revoke
18 : *
19 : * the output script is SQL that is understood by PostgreSQL
20 : *
21 : * Basic process in a restore operation is:
22 : *
23 : * Open the Archive and read the TOC.
24 : * Set flags in TOC entries, and *maybe* reorder them.
25 : * Generate script to stdout
26 : * Exit
