Notes on pg_dump
|
||
|
|
================
|
||
|
|
|
||
|
|
pg_dump, by default, still outputs text files.
|
||
|
|
|
||
|
|
pg_dumpall forces all pg_dump output to be text, since it also outputs text into the same output stream.
|
||
|
|
|
||
|
|
The plain text output format can not be used as input into pg_restore.
|
||
|
|
|
||
|
|
|
||
|
|
To dump a database into the next custom format, type:
|
||
|
|
|
||
|
|
pg_dump <db-name> -Fc > <backup-file>
|
||
|
|
|
||
|
|
To restore, try
|
||
|
|
|
||
|
|
To list contents:
|
||
|
|
|
||
|
|
pg_restore -l <backup-file> | less
|
||
|
|
|
||
|
|
or to list tables:
|
||
|
|
|
||
|
|
pg_restore <backup-file> --table | less
|
||
|
|
|
||
|
|
or to list in a differnet orderL
|
||
|
|
|
||
|
|
pg_restore <backup-file> -l --oid --rearrange | less
|
||
|
|
|
||
|
|
Once you are happy with the list, just remove the '-l', and an SQL script will be output.
|
||
|
|
|
||
|
|
|
||
|
|
You can also dump a listing:
|
||
|
|
|
||
|
|
pg_restore -l <backup-file> > toc.lis
|
||
|
|
or
|
||
|
|
pg_restore -l <backup-file> -f toc.lis
|
||
|
|
|
||
|
|
edit it, and rearrange the lines (or delete some):
|
||
|
|
|
||
|
|
vi toc.lis
|
||
|
|
|
||
|
|
then use it to restore selected items:
|
||
|
|
|
||
|
|
pg_restore <backup-file> --use=toc.lis -l | less
|
||
|
|
|
||
|
|
When you like the list, type
|
||
|
|
|
||
|
|
pg_restore backup.bck --use=toc.lis > script.sql
|
||
|
|
|
||
|
|
or, simply:
|
||
|
|
|
||
|
|
createdb newdbname
|
||
|
|
pg_restore backup.bck --use=toc.lis | psql newdbname
|
||
|
