Thanks for your comments.
I added the definition of sepgsql_setcon function to sepgsql.sql.in file,
in addition to patch rebasing.

The "default" security policy does not permit dynamic domain transition
even if unconfined domain, in contradiction to its name.
(IMO, it is fair enough design to avoid single point of failure like root user.)
The security policy of regression test contains a set of rules to reduce
categories assigned to unconfined domain.
So, could you try the following steps.
1. Build the latest policy
% make -f /usr/share/selinux/devel/Makefile -C contrib/sepgsql
2. Install the policy module
% sudo semodule -i contrib/sepgsql/sepgsql-regtest.pp
3. Turn on the sepgsql_regression_test_mode
% sudo setsebool -P sepgsql_regression_test_mode=1
I believe it allows to switch security label of the client, as long as we try to
reduce categories.
Thanks,
