pg_dump_anon not working with file output

Hello,

When using pg_dump_anon with -f, --file=FILENAME output file

I don't have any data dumped. While looking at the script I've found that this line : dumped_tables=`$DUMP $exclude_table |awk '/^CREATE TABLE /{ print $3 }'`

Return an empty list. This is because the $DUMP command contains the -f option and does not output to stdout (and so awk has nothing to transform).

I'm not sure what is the best way to fix this.

Thanks,
