But these misses the "directory", "module_pathname" and "encoding" extension specific informations and these are not available even with extension specific functions also. There are some extension that differs in extension name to library name. The pgpool_recovery extension library name is pgpool-recovery.so, '_' to '-'. While we are developing some tool on top of PostgreSQL, we found out this problem and it can be solved easily if the server expose the details that i have and got it from the extension control file.
Any opinion in adding a new view like "pg_available_extension_details" to display all extension control file columns? or Adding them to the existing view is good?
