pg_dump and table exclusion: multiple patterns

hello,

I'm trying to export a schema with multiple table exclusions:

pg_dump -i -v -nXXX -T
'*20((08[0-9]+)|(09[0-9]+)|(100[1-8][0-9]+)|(1009[0-1][0-9]+))'

unfortunately, the filter does not work as expected.(no table at all
are excluded)

when I try the same pattern with psql dt\, I get the expected list of
tables to exclude...

pg_dump --version

pg_dump (PostgreSQL) 8.3.9

I'd appreciate some help.

best regards,

Marc Mamin
