I am new to contributing in PostgreSQL and I've just installed the source code and built the system successfully from the source code and trying to find a bug to start working on but I face some problems with the pgsql-bugs mailing list as I can't filter them by which are solved and which are not, which are assigned to somebody and which are not, which is first good issue and which are advanced, so I am totally lost in this mailing list with nearly no useful information that help me get an issue and start working on it to submit my first patch. So if anyone faced the same problem please let me know.
