We recommend looking at psql's "-E" output to help understand the system catalogs, but in some cases (particularly table displays) there's a bunch of rather impenetrable SQL there. As a small improvement, label each query issued by describe.c with a short description of its purpose. The code is arranged so that the labels also appear as SQL comments in the server log, if the server is logging these commands. We could expand this policy to every use of PSQLexec(), but most of the ones outside describe.c are issuing simple commands like "BEGIN" or "COMMIT", which don't seem to need such glosses. I did add labels to the commands issued by \sf, \sv and friends. Also, make the -E and log output for hidden queries say "INTERNAL QUERY" not just "QUERY", to distinguish them from user-written queries.
