Hi, One consequence of using the "C" collation in the catalog versus the db collation is that pg_dump -t with a regexp may not find the same tables as before. It happens when these conditions are all met: - the collation of the database is not "C" - the regexp has locale-dependant parts - the names to match include characters that are sensitive to locale-dependant matching
For instance a table named "rapport_journée_12" in an fr_FR.UTF-8 db used to be found by pg_dump -t 'rapport_\w+_\d+', and is now missed in the devel version. It seems that to fix that, we could qualify the references to columns such as "relname" and "schema_name" with COLLATE "default" clauses in the queries that use pattern-matching in client-side tools, AFAICS pg_dump and psql. Before going any further with this idea, is there agreement that it's an issue to address and does this look like the best way to do that?
