The attached patch seems to work:
alvherre=# create table pg_catalog.foo (a int);
ERROR: permission denied for schema pg_catalog
It passes regression tests for both core and contrib.
I notice that contrib/adminpack now fails, though (why doesn't this
module have a regression test?):
alvherre=# create extension adminpack;
ERROR: permission denied for schema pg_catalog
It sounds hard to support that without some other special hack. Not
sure what to do here. Have adminpack set allowSystemTableMods somehow?
I grepped for other occurences of "pg_catalog" in contrib SQL scripts,
and all other modules seem to work (didn't try sepgsql):
$ rgrep -l pg_catalog */*sql | cut -d/ -f1 | while read module; do echo module: $module; psql -c "create extension $module"; done
module: adminpack
