pg_dump question (exclude schemas)

[Jay Vee <jvsrvcs@xxxxxxxxx>]

I want to backup a database but exclude certain schemas with a patter.

I have 100 schemas with the pattern:  'sch_000', 'sch_001',  and so on.

Will this work?

$pg_dump <other_options>  --exclude-schema='sch_*'

this does not seem to exclude all schemas with this pattern  ( 'sch_*' ), anything wrong here?

thanks

J.V.
