 Hello every body!!  I have a quesyion respect pg_dump...........

I need to backup the db structure, I suposse that I do with pg_dump -s, but I want to restore but just with some tables with the db catalogues, can I do this?, I mean, restore al the db structure without data and after restore the data of the catalogues tables??

Don't worry about the catalog tables. If all you want is the schema dumped and restored then, yes, use the -s flag. The data in the catalog tables is built as the schema is rebuilt during the restore, i.e postgres takes care of those for you.
