No, "applied" is "f" (false), meaning that the setting is not actually usable. I'm a little surprised that it seems to have gotten into your live session anyway, although perhaps that's because the postmaster can't really validate it at startup.

"public.pg" is certainly not a standard (as in built-in) text search configuration name. Maybe that value was installed by some bit of software that failed to install the configuration to go with it, or only put the configuration into one database not everywhere in your installation?
All right, then it means that this is a configuration error, and it is not a problem with the database instance and its live data. That was my main concern. I'll just simply change this in the conf file and reload the config.
