Why does Red Hat Satellite 5.6 installation fail with SELinux errors when using a separate filesystem for the PostgreSQL database?

Issue

• When installing Satellite 5.6 using the embedded PostgreSQL database I get the following error message:

* Setting up Selinux..
** Database: Setting up database connection for PostgreSQL backend.
** Database: Installing the database:
** Database: This is a long process that is logged in:
** Database:   /var/log/rhn/install_db.log
*** Progress: #
Could not install database.

• Checking the resulting /var/log/rhn/install_db.log log file shows that the installer is complaining about incorrect security context in /var/lib/pgsql:

# cat /var/log/rhn/install_db.log

The directory "/var/lib/pgsql" does not seem to have correct SELinux context.

Please fix the SELinux context by running:

    restorecon -Rv /var/lib/pgsql

• Security contexts in /var/lib/pgsql seem correct:

# ls -ldZ /var/lib/pgsql
drwx------. postgres postgres system_u:object_r:postgresql_db_t:s0 /var/lib/pgsql
# 
# ls -lZ /var/lib/pgsql
drwx------. postgres postgres system_u:object_r:postgresql_db_t:s0 backups
drwx------. postgres postgres system_u:object_r:postgresql_db_t:s0 data
drwx------. root     root     system_u:object_r:lost_found_t:s0 lost+found
-rw-------. postgres postgres unconfined_u:object_r:postgresql_log_t:s0 pgstartup.log

• Applying the command suggested by /var/log/rhn/install_db.log changes the security context of lost+found directory and allows the installation to proceed.

# restorecon -Rv /var/lib/pgsql
restorecon reset /var/lib/pgsql/lost+found context system_u:object_r:lost_found_t:s0->system_u:object_r:postgresql_db_t:s0

• Should not lost-found directory have system_u:object_r:lost_found_t:s0 security context?
