Hello Dagfinn,
The attached patch makes the first mention of another system catalog or view (as well as pg_hba.conf in pg_hba_file_lines) a link, for easier navigation.
Why only the first mention? It seems unlikely that I would ever read such chapter linearly, and even so that I would want to jump especially on the first occurrence but not on others, so ISTM that it should be done all mentions?
