--verbose messages, which had not been considered so far. Output to the terminal should okay now; comments written into the dump are still English only, which may or may not be the desirable thing.

|
* 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
|

* Modifications - 28-Jun-2000 - pjw@rhyme.com.au
|
|
*
|
|
* Initial version. Command processing taken from original pg_dump.
|
|
*
|
|
* Modifications - 28-Jul-2000 - pjw@rhyme.com.au (1.45)
|
|
*
|
|
* Added --create, --no-owner, --superuser, --no-reconnect (pg_dump & pg_restore)
|
|
* Added code to dump 'Create Schema' statement (pg_dump)
|
|
* Don't bother to disable/enable triggers if we don't have a superuser (pg_restore)
|
|
* Cleaned up code for reconnecting to database.
|
|
* Force a reconnect as superuser before enabling/disabling triggers.
|
|
*
|
|
* Modifications - 6-Mar-2001 - pjw@rhyme.com.au
|
|
* Change -U option to -L to allow -U to specify username in future.
