Not directly with pg_dump. You could create a table (create table customers_1 as select * from customers where id=11) and dump that but remember to change the tablename in the dump file or after loading it. You dont get any pk/fk/indexes on the table definition. You could also use copy to stdout/stdin. eg dump psql -d dbname -c "create temp table dump as select * from customers where id=11; copy dump to stdout;" >dumpfile eg restore psql -d newdb -c "copy customers from stdin" <dumpfile You might need to play around with supplying username/password. klint. +---------------------------------------+-----------------+ : Klint Gore : "Non rhyming : : EMail : kg@xxxxxxxxxxxxxx : slang - the : : Snail : A.B.R.I. : possibilities : : Mail University of New England : are useless" : : Armidale NSW 2351 Australia : L.J.J. : : Fax : +61 2 6772 5376 : : +---------------------------------------+-----------------+
