Re: How to fully restore a single table from a custom dump? - Mailing list pgsql-admin

Hi,

If you use the directory dump method, -Fd, then you could generate an editable listing where you can selectively remove stuff that you don't want to restore, just keeping the stuff related to your specific table.   You run pg_restore once to generate the listing.  Then run pg_restore again using that modified listing to load into the target database. See the pg_restore docs for exact syntax.

Hello,

 

I just realized that using

 

pg_restore -t some_table ... some_dump_file

 

doesn't restore things like identity attributes

or indexes on the specified table.

 

The dump contains much more than just that table, so simply

using pg_restore without -t is not an option.

 

While I could extract the indexes manually using some clever regex

on the index names, I don't see a way to make sure that identity

definitions (or sequence values) are restored properly for the selected table.

 

Any ideas, how I can _fully_ restore a single table from a custom dump?

Creating a list of contained items and restoring some of them works the same with custom dumps. Directory dumps have no advantage here.

Just comment out all items you don't want to restore by putting a ; in front of the lines or delete the unwanted lines altogether and restore.

Best regards,

Holger
